Low RF Susceptibility DirectDrive Stereo Head-

phone Amplifier with 1.8V Compatible Shutdown

C/MAX9724D

General Description

Features

♦ Improved RF Noise Rejection (Up to 67dB Over

The MAX9724C/MAX9724D stereo headphone ampli-

fiers are designed for portable equipment where board

space is at a premium. These devices use a unique,

DirectDrive^®architecture to produce a ground-refer-

enced output from a single supply, eliminating the need

for large DC-blocking capacitors, saving cost, board

space, and component height. The MAX9724 sup-

presses RF radiation received by input and supply

traces acting as antennas and prevents the amplifier

from demodulating the coupled noise. The MAX9724C

offers an externally adjustable gain while the

MAX9724D has an internally preset gain of -1.5V/V. The

MAX9724C/MAX9724D deliver up to 60mW per channel

into a 32Ω load and have low 0.02% THD+N. An 80dB

at 1kHz power-supply rejection ratio (PSRR) allows

these devices to operate from noisy digital supplies

without an additional linear regulator. Comprehensive

click-and-pop circuitry suppresses audible clicks and

pops on startup and shutdown.

Typical Amplifiers)

♦ No Bulky DC-Blocking Capacitors Required

♦ Low-Power Shutdown Mode, < 0.1µA

♦ Adjustable Gain (MAX9724C) or Fixed -1.5V/V

Gain (MAX9724D)

♦ Low 0.02% THD+N

♦ High PSRR (80dB at 1kHz) Eliminates LDO

♦ Integrated Click-and-Pop Suppression

♦ 2.5V to 5.5V Single-Supply Operation

♦ Low Quiescent Current (3.5mA)

♦ Available in Space-Saving Packages

12-Bump UCSP (1.5mm x 2mm)

12-Pin Thin QFN (3mm x 3mm x 0.8mm)

GAIN (V/V) PIN-PACKAGE

The MAX9724C/MAX9724D operate from a single 2.5V

to 5.5V supply, consume only 3.5mA 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

12-bump UCSP™ (1.5mm x 2mm) and 12-pin thin QFN

(3mm x 3mm x 0.8mm) packages.
