DirectDrive, Headphone Amplifier with

BassMax, I C, Volume and Gain Control

General Description

Features

♦ 105mW DirectDrive Headphone Amplifier

The MAX9726 stereo, DirectDrive™, headphone amplifier

with BassMax and volume control is ideal for portable

audio applications where space is at a premium and per-

formance is essential. The MAX9726 operates from a sin-

gle 2.7V to 5.5V power supply and includes features that

reduce external component count, system cost, board

space, and offer improved audio reproduction. High

85dB PSRR makes the MAX9726 ideal for direct connec-

tion to a battery-powered supply and eliminates the need

for a dedicated LDO. The MAX9726 features Maxim’s

industry-leading click-and-pop suppression circuitry,

which reduces/eliminates audible transients during

power-up and power-down.

Eliminates Bulky DC-Blocking Capacitors

♦ 2.7V to 5.5V Single-Supply Operation

♦ Integrated 64-Level Volume Control

♦ High 85dB PSRR at 1kHz

♦ Software-Enabled Bass Boost (BassMax)

♦ Industry-Leading Click-and-Pop Suppression

♦ ±7.5kV HBM ESD-Protected Headphone Outputs

♦ Short-Circuit and Thermal-Overload Protection

♦ Low-Power Shutdown Mode (8µA)

♦ Low 0.02% THD+N

The headphone amplifier uses Maxim’s patented^†

DirectDrive architecture that produces a ground-refer-

enced output from a single supply, eliminating the need

for large DC-blocking capacitors. The headphone ampli-

fiers deliver 105mW into a 32Ω load and feature low

0.02% THD+N.

♦ I C/SMBus-Compatible Interface

♦ Available in Space-Saving, Thermally Efficient

Packages

20-Bump UCSP (2mm x 2.5mm x 0.62mm)

20-Pin TQFN (4mm x 4mm x 0.75mm)

Ordering Information

The BassMax feature boosts the bass response of the

amplifier, improving audio reproduction when using inex-

pensive headphones. The integrated volume control fea-

tures 64 discrete volume levels, eliminating the need for

an external potentiometer. External resistors set the

MAX9726’s overall gain allowing for custom gain settings.

BassMax and the volume control are enabled through the

I²C/SMBus^™-compatible interface. Shutdown can be con-

trolled through the hardware or software interface.

Note: All devices specified over the -40°C to +85°C operating

range.

The MAX9726 consumes only 5.5mA of supply current,

provides short-circuit and thermal-overload protection,

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

perature range. The MAX9726 is available in a tiny

(2mm x 2.5mm x 0.62mm) 20-bump chip-scale pack-

age (UCSP™) and a 20-pin TQFN package (4mm x

4mm x 0.75mm).
