5 W, Two-channel Power Amplifier with Very Few
External Parts
Overview
The LA4485 is a 5 W, two-channel power amplifier IC that
requires a minimum of external parts, making it ideal for radio
cassette players and car stereo equipment.
The LA4485 eliminates the need for bootstrap capacitors,
negative feedback capacitors, and oscillation prevention CR
parts, all of which were necessities for power ICs previously.
All of these functions are now on chip, keeping the number of
external parts to an absolute minimum. The LA4485 is part of
the Power (Stylish Power) Series, and supports two modes:
dual and BTL.

IC Usage Notes
Maximum ratings
Care must be taken when operating the LA4485 close to the maximum ratings as small changes in the operating conditions can
cause the maximum ratings to be exceeded, thereby breakdown will be caused.
Printed circuit board connections
Care must be taken when designing the circuit of printed board so as not to form feedback loops, particularly with the small-signal
and large-signal ground connections.
Notes on LA4485 heatsink mounting
1. Mounting torque must be in the range 39 to 59 Nvcm.
2. The spacing of the tapped holes in the heatsink must match the spacing of the holes in the IC tab.
3. Use screws with heads equivalent to truss head machine screws and binding head machine screws stipulated by JIS for the
mounting screws. Furthermore, washers must be used to protect the surface of the IC tab.
4. Make sure that there is no foreign matter, such as cutting debris, between the IC tab and the heatsink. If a heat conducting
compound is applied between the contact surfaces, make sure that it is spread uniformly over the entire surface.
5. Because the heatsink mounting tab and the heatsink are at the same electric potential as the chip’s GND (large signal GND),
care must be taken when mounting the heatsink on more than one device.
6. The heatsink must be mounted before soldering the pins to the PCB.

Dual-mode Operation Notes
.Use the input capacitor CIN in the range of 0.22 µF to 1.0 µF.
Parameter CIN = 0.22 µF CIN = 1.0 µF
Start-up time (ts) 0.15 s 0.25 s
Attack noise when using the muting function Somewhat noticeable Good
Speaker turn-ON transient noise increased significantly when CIN is 2.2 µF or greater.
.The DC (filter) capacitor should be 100 µF or greater.
Parameter 100 µF or less 100 µF or more
Standby-off output capacitor
discharge circuit *1. Does not operate.
Repeated on/off: poor *2. Operates normally.
On/off: good
Ripple rejection ratio (SVRR) Somewhat worse
40 dB Good
50 dB
VNrise rate when main or
standby is turned ‘‘on’’ Fast Slow
Note:
*1. Slow as a result of natural discharge.
*2. Approximately 0.3 seconds as a result of forced discharge.
.Use the standby supply capacitor in the range of 0.22 µF to 0.47 µF.
The VNtrace for standby OFF changes and speaker turn-ON transient noise is increased significantly when the capacitor is 1 µF
or greater. If the standby function is not used, this capacitor must be removed and pin 9 must be pulled up to the power supply.
.The output capacitor’s recommended value for COis 1,000 µF.
Smaller capacitance will worsen the roll-off frequency fLand POin a low range.
.The recommended power supply capacitor is approximately 2,200 µF, but other capacitors than 2,200 µF can be used according
to the application’s design.
Using a capacitor with this value, the load on the supply can be as high as 56 Ωwhile still providing good supply stability
during momentary supply glitches. Note that using a 0.15 µF capacitor can cause oscillations if the supply impedance increases.
(Example: Mild oscillation results if the power supply capacitor is open.)

.Insert capacitors of 1000 pF between each input and ground to prevent external noise.
.When the load (RL) or the supply voltage (VCC) is increased, turning the standby switch or the main switch on under strong
input conditions will activate the IC’s internal pseudo ASO protection circuit for the upper power transistor (VCE ×ICP). This
causes output oscillations or intermittent operation (The reference area is shown in Figure 1 below). However, strong input tests
after the bias has stabilized have no problems. They also protect the upper power transistors close to the limits of ASO when all
signal switches are on. Therefore, when using this IC under these conditions, the circuit design should obey the following
condition:
Signal generation time > Start-up time of the power amplifier IC
or some other method of attaining the zero-volume condition should be adopted.
.An undervoltage protection circuit operates when the voltage is 7.5 V or lower.
Strong signal input after switch-ON is OK.
In BTL-mode operation, the load is RL×2
This figure shows the pseudo ASO protection area when strong signal is input, and switch is ON:
the upper power transistors have an area where VCE ×ICP load is caused.

BTL-mode Operation Notes
In BTL mode, channel 1 should be non-inverted and channel 2 should be inverted.
.Use the input capacitor CIN in the range 0.22 µF to 2.2 µF.
.Use the standby supply capacitor in the range 0.22 µF to 1.0 µF.
When the capacitor is 2.2 µF or more, the VNtrace for standby-off changes, and the switching noise increases significantly.
.The recommended DC (filter) capacitor is 100 µF or greater.
.The BTL-mode coupling capacitor should be 2.2 µF.
When this capacitor is decreased, the output power is decreased. However, when this capacitor is increased, speaker
turn-ON transient noise is increased significantly.
.In BTL mode, the ripple rejection ratio (SVRR) is approximately 40 dB.
This is because the output ripple portion of the noninverted side penetrates the BTL coupling end, so that ripple on the
inverted side is large. The following method is described as one external measure:
This measure yields an SVRR of approximately 50 dB. Note that the Rx loss voltage is approximately 1 V, and the POloss is
about 1.0 to 1.5 W (to the 15 W level).

.Taking BTL coupling into consideration, the output-to-supply/output-to-ground protector is two-sided in order to protect both the
IC and the speaker.
When using this method (simultaneously shorting the outputs to supply and to ground)
In BTL mode, the IC protection function works even in noninverted output →output-to-supply mode, inverted output →
output-to-ground mode. (The reverse is also OK.)

.Power supply positive surge
The power supply line positive surge breakdown margin has been increased by using the built-in overvoltage protection circuits
(VCCX = 28 V) to cut off all bias circuits/change the base-emitter reverse of the output stage. In other words, the breakdown
margin is being raised by changing output stage groups that operate as the VCEO (VCER) type to the VCES (VCBO) type.

.Test of application of +VCC to output pins
If the power supply pin is floating under the power supply capacitor insertion conditions, and +VCC comes into contact with
output lines (a) and (b) as shown in the diagram above, the IC’s internal upper power transistor will generally be damaged. The
LA4485 has a protective bypass circuit on chip. However, it is dangerous if the power supply capacitor is greater than 2200 µF.
