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.

Figure 1 Block diagram

The voltage gain of Amp. 1

: GV1 = 0dB

The voltage gain of Amp. 2A, B

: GV2 = 20dB

The voltage gain of BLT Connection : GV (BTL) = 6dB

Therefore, the total voltage gain is decided by expression below.

GV = GV1 + GV2 + GV (BTL) = 0 + 20 + 6 = 26dB
