60mW, DirectDrive, Stereo Headphone Amplifier

with Low RF Susceptibility and Shutdown

General Description

Features

The MAX9724A/MAX9724B stereo headphone ampli-

fiers are designed for portable equipment where board

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

patented^†DirectDrive™ architecture to produce a

ground-referenced output from a single supply, elimi-

nating the need for large DC-blocking capacitors, sav-

ing cost, board space, and component height. The

MAX9724 suppresses RF radiation received by input

and supply traces acting as antennas and prevents the

amplifer from demodulating the coupled noise. The

MAX9724A offers an externally adjustable gain while

the MAX9724B has an internally preset gain of -1.5V/V.

The MAX9724A/MAX9724B 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 sup-

plies without an additional linear regulator.

Comprehensive click-and-pop circuitry suppresses

audible clicks and pops on startup and shutdown.

♦ Improved RF Noise Rejection (Up to 67dB Over

Typical Amplifiers)

♦ No Bulky DC-Blocking Capacitors Required

♦ Low-Power Shutdown Mode, < 0.1µA

♦ Adjustable Gain (MAX9724A) or Fixed -1.5V/V

Gain (MAX9724B)

♦ Low 0.02% THD+N

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

♦ Integrated Click-and-Pop Suppression

♦ 2.7V 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)

MARK

The MAX9724A/MAX9724B operate from a single 2.7V

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.
