TDA7575PDTR

Overview

The TDA7575PD is a dual-bridge Class AB audio amplifier utilizing MultiPower BCD technology and DMOS output stages, designed for automotive radio applications. It operates on a single supply voltage ranging from 8 V to 18 V. The device delivers up to 2x75 W into 2 Ω loads or 1x150 W into 1 Ω load in single-channel configuration. Key electrical parameters include a maximum output current of 8 A, a typical gain of 26 dB (selectable to 12 dB), and a THD+N of 0.03% at low power levels. It features differential inputs and is housed in a PowerSO-36 package.
