Dual 15 W BTL power IC for car audio
■ Overview
11.3±0.3
7.7±0.3
Unit : mm
The AN7196K is an audio power IC developed for the
sound output of car audio (dual 15 W). Especially, this
circuit has solved the problem of heat radiation design
inherent to a single chip IC with 4-channel audio ouputs
and realized a corresponding space saving at the same
time.

R1.8
In addition, it is incorporating various protection cir-
cuits to protect the IC from destruction by GND-open
short-circuit to GND and power supply surge which are
the most important subjects of power IC protection, and
the IC will largely contribute to a high reliability design
of equipment.
It is also incorporating the industry's first perfect
muting circuit, which is free from shock noise, so that a
shock noise design under the set transient condition can
be made easily when the muting circuit is used together
with its standby function.

The AN7196K is pin compatible with the AN7191NK
(dual 20 W), so that the identical pattern design is allowed
for high-class types as well as popular types.
■ Features
• Built-in various protection circuits (realizing high breakdown voltage against destruction )
Power supply surge breakdown voltage of 100 V or more
Ground open breakdown voltage of 16 V or more
• Built-in standby function (free from shock noise at standby on/off)
• Built-in muting function (the industry's first)
Free from shock noise at mute-on/off
Adapting attenuator method so that abnormal sound due to waveform deformation is not generated
Attack time, recovery time of 50 ms or less
• Space saving design is possible with a small size package
A heat radiation design that has been a problem particularly in a 4-ch. single chip IC can be done by the conventional
method.
• Reduction in external components (parts reduction to half compared with the AN7176K)
It eliminates the need for NF and BS electrolytic capacitors,
Muting function is unnecessary
Power supply choke coil is unnecessary
• Provided with beep sound input pin
• Pin compatible with the AN7191NK (dual 20 W)
■ Applications
• Car audio

■ Usage Notes
1. Always attach an outside heat sink to use the chip. In addition, the outside heat sink must be fastened onto a
chassis for use.
2. Connect the cooling fin to GND potential.
3. Avoid short-circuit to VCC and short-circuit to GND, and load short-circuit.
4. The temperature protection circuit will be actuated at Tj = approx. 150°C, but it is automatically reset when the
chip temperature drops below the above set level.
5. The overvoltage protection circuit starts its operation at VCC = approx. 20 V.
6. Take into consideration the heat radiation design particularly when VCC is set high or when the load is 2 Ω.
7. When the beep sound function is not used, open the beep sound input pin (pin 10) or connect it to pin 9 with
around 0.01 µF capacitor.
8. Connect only pin 9 (ground, signal source) to the signal GND of the amplifier in the previous stage. The
characteristics such as distortion, etc. will be improved.
