19-3465; Rev 2; 11/07

1V, Low-Power, DirectDrive, Stereo Headphone

Amplifier with Shutdown

General Description

Features

♦ Low Quiescent Current:

2.1mA (MAX9725A–MAX9725D)

2.3mA (MAX9725E)

The MAX9725A–MAX9725D fixed-gain, stereo head-

phone amplifiers are ideal for portable equipment where

board space is at a premium. The MAX9725E offers the

flexibility to adjust the gain with external input and feed-

back resistors. The MAX9725A–MAX9725E use a unique,

patented DirectDrive^TMarchitecture to produce a ground-

referenced output from a single supply, eliminating the

need for large DC-blocking capacitors, saving cost,

board space, and component height. Fixed gains of

-2V/V (MAX9725A), -1.5V/V (MAX9725B), -1V/V

(MAX9725C), and -4V/V (MAX9725D) further reduce

external component count. The adjustable gain of the

MAX9725E DirectDrive headphone amplifier allows for

any gain down to -1V/V using external resistors.

♦ Single-Cell, 0.9V to 1.8V Single-Supply Operation

♦ Fixed Gain Eliminates External Feedback Network

MAX9725A: -2V/V

MAX9725B: -1.5V/V

MAX9725C: -1V/V

MAX9725D: -4V/V

♦ Adjustable Gain with External Input and Feedback

Resistors

MAX9725E: Minimum Stable Gain of -1V/V

♦ Ground-Referenced Outputs Eliminate DC Bias

♦ No Degradation of Low-Frequency Response Due

to Output Capacitors

♦ 20mW per Channel into 32Ω

♦ Low 0.006% THD+N

♦ High PSRR (80dB at 1kHz)

♦ Integrated Click-and-Pop Suppression

♦ Low-Power Shutdown Control

♦ Short-Circuit Protection

The MAX9725 delivers up to 20mW per channel into a

32Ω load and achieves 0.006% THD+N. An 80dB at 1kHz

power-supply rejection ratio (PSRR) allows the MAX9725

to operate from noisy digital supplies without an additional

linear regulator. The MAX9725 includes ±8kV ESD protec-

tion on the headphone output. Comprehensive click-and-

pop circuitry suppresses audible clicks and pops at

startup and shutdown. A low-power shutdown mode

reduces supply current to 0.6µA (typ).

♦ ±8kV ESD-Protected Amplifier Outputs

♦ Available in Space-Saving Packages

12-Bump UCSP (1.54mm x 2.02mm x 0.6mm)

12-Pin Thin QFN (4mm x 4mm x 0.8mm)

The MAX9725 operates from a single 0.9V to 1.8V supply,

allowing the device to be powered directly from a single

AA or AAA battery. The MAX9725 consumes only

2.1mA of supply current, provides short-circuit protection,

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

perature range. The MAX9725 is available in a tiny

(1.54mm x 2.02mm x 0.6mm) 12-bump chip-scale

package (UCSP™) and a 12-pin thin QFN package

(4mm x 4mm x 0.8mm).
