TS4974 - 1W Differential Audio Power Amplifier

General Description

At 3.3v, the TS4974 is a dual power audio amplifier capable of delivering 380mW of www.DataSheet4U.com continuous RMS ouput power into a 8Ω bridgedtied loads with 1% THD+N.

An external standby mode control reduces the supply current to less than 2µA.

Key Features

  • a 16 step digital volume control through two discrete control Up and Down pins. The start-up gain is internally fixed to -12dB. An integrated debounce system prevents voltage pikes on UP/DOWN pins during volume control mode to be taken into account during a debounce time of 10ms (typ. ). TS4974IQ - Pinout VINVIN+ BYPASS.
