The TDA7372A is a new technology class AB quad channels Audio Power Amplifier designed for car radio applications. It has high power capability, minimum external component count, internally fixed gain, ST-BY and mute function, and various protection features.
The TDA7372A is a new technology Class AB quad channel audio power amplifier in a Multiwatt15 package, specifically designed for car radio applications. It features a fully complementary PNP/NPN output configuration that delivers a rail-to-rail voltage swing without the need for bootstrap capacitors or external compensation.
The device includes built-in protections such as AC and DC output short circuit protection, soft thermal limiting, and load dump voltage protection. Key features include an internally fixed gain of 20dB, ST-BY and MUTE functions compatible with CMOS logic, and a programmable turn-on delay to prevent audible pops.
