TB2922HQ Product details

Description

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 : GV2 = 20dB The voltage gain of BTL connection : GV (BTL) = 6dB Therefore, the total voltage gain is decided by expression below.GV = GV1 + GV

Features
