5V, Differential Input, DirectDrive, 130mW

Stereo Headphone Amplifiers with Shutdown

General Description

Features

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, eliminat-

ing 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).

The MAX9722A/MAX9722B deliver up to 70mW per

channel into a 16Ω load or 130mW into a 32Ω load and

have low 0.009% THD+N. An 80dB at 217Hz power-sup-

ply rejection ratio (PSRR) allows these devices to operate

from noisy digital supplies without an additional linear

regulator. The MAX9722A/MAX9722B include 8kV ꢀSD

protection on the headphone outputs. Comprehensive

anticlick-and-pop circuitry suppresses audible clicks

and pops on startup and shutdown. A low-power shut-

down mode reduces the supply current to 0.1µA.

ꢀ 2.4V to 5.5V Single-Supply Operation

ꢀ High PSRR (80dB at 217Hz) Eliminates LDO

ꢀ No Bulky DC-Blocking Capacitors Required

ꢀ Ground-Referenced Outputs Eliminate DC Bias

Voltage on Headphone Ground Pin

ꢀ No Degradation of Low-Frequency Response Due

to Output Capacitors

ꢀ Differential Inputs for Enhanced Noise

Cancellation

ꢀ Adjustable Gain (MAX9722A) or Fixed -2V/V Gain

(MAX9722B)

ꢀ 130mW per Channel into 32Ω

ꢀ Low 0.009% THD+N

ꢀ Integrated Click-and-Pop Suppression

ꢀ Low Quiescent Current (5.5mA)

ꢀ Short-Circuit and Thermal-Overload Protection

The MAX9722A/MAX9722B operate from a single 2.4V

to 5.5V supply, consume only 5.5mA of supply current,

feature short-circuit and thermal-overload protection,

and are specified over the extended -40°C to +85°C

temperature range. The devices are available in tiny

16-pin thin QFN (3mm ✕ 3mm ✕ 0.8mm) and 16-pin

TSSOP packages.
