APA2121 - Stereo 2-W Audio Power Amplifier

Download the APA2121 datasheet PDF. This datasheet also covers the APA2120 variant, as both devices belong to the same stereo 2-w audio power amplifier family and are provided as variant models within a single manufacturer datasheet.

Description

APA2120/1 is a monolithic integrated circuit, which provides precise DC volume control, and a stereo bridged audio power amplifiers is capable of producing 2.7W(2.

0W) into 3Ω with less than 10% (1.0%)THD+N.

Features

  • Low Operating Current with 14mA.
  • Improved Depop Circuitry to Eliminate Turn-on and Turn-off Transients in Outputs.
  • High PSRR.
  • 32 Steps Volume Adjustable by DC Voltage with Hysteresis.
  • 2W Per Channel Output Power into 4Ω Load at 5V, BTL Mode.
  • Two Output Modes Allowable with BTL and SE Modes Selected by SE/BTL Pin.
  • Low Current Consumption in Shutdown Mode (50µA).
  • Short Circuit Protection.
  • Power off Depop Circuit Inte.
