TB2922HQ Dual Audio Power Amplifier

TB2922HQ Dual Audio Power Amplifier

is made only on the single channel) 1. Voltage Gain Adjustment This IC has no NF (negative feedback) Pins. Therefore, the voltage gain can not be adjusted, but it makes the device a space and total costs saver. Amp. 2A Amp. 1 Input www.DataSheet4U.com Amp. 2B Figure 1 Block Diagram The voltage gain of amp.1 : GV1 = 8dB The voltage gain of amp.2A, B : GV.
