MAX9722B Datasheet 130mw Stereo Headphone Amplifiers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: www.DataSheet4U.com 19-3049; Rev 0; 10/03 ILABLE N KIT AVA EVALUATIO 5V, Differential Input, DirectDrive, 130mW Stereo Headphone Amplifiers with.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX9722A/MAX9722B stereo headphone amplifiers are designed for portable equipment where board space is at a premium.

The MAX9722A/MAX9722B use a unique, patented DirectDrive architecture to produce a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, which saves cost, board space, and component height.

Additionally, the gain of the amplifier is set internally (-2V/V, MAX9722B) or adjusted externally (MAX9722A).

Key Features

  • o 2.4V to 5.5V Single-Supply Operation o High PSRR (80dB at 217Hz) Eliminates LDO o No Bulky DC-Blocking Capacitors Required o Ground-Referenced Outputs Eliminate DC Bias Voltage on Headphone Ground Pin o No Degradation of Low-Frequency Response Due to Output Capacitors o Differential Inputs for Enhanced Noise Cancellation o Adjustable Gain (MAX9722A) or Fixed -2V/V Gain (MAX9722B) o 130mW per Channel into 32Ω o Low 0.009% THD+N o Integrated Click-and-Pop Suppression o Low Quiescent Current (5.5.
