Caution And Application Method
(description is made only on the single channel.)
1. Voltage gain adjustment
This IC has no NF (negative feedback) terminals. Therefore, the voltage gain can’t adjusted, but it makes the
device a space and total costs saver.
The voltage gain of amp. 1: GV1 = 0 dB
The voltage gain of amp. 2A, B: GV2 = 28 dB
The voltage gain of BTL connection: GV (BTL) = 6 dB
Therefore, the total voltage gain is decided by expression below.
GV = GV1 + GV2 + GV (BTL) = 0 + 28 + 6 = 34 dB
2. Standby SW function
By means of controlling pin(2) (standby terminal) to high
and low, the power supply can be set to on and off.
The threshold voltage of pin(2) is set at about 3V (typ.),
and the power supply current is about 100 A (typ.) at the
standby state.
Control voltage of pin(2): V (SB)

Adjustage of standby SW
(1) Since VCC can directly be controlled to on or off by the
microcomputer, the switching relay can be omitted.
(2) Since the control current is microscopic, the switching relay of small current capacity is satisfactory for
switching
