Stereo Audio DAC with DirectDrive

Headphone Amplifier

General Description

Features

The MAX9850 is a low-power, high-performance stereo

audio DAC with an integrated DirectDrive headphone

amplifier. The MAX9850 is designed to meet the board

space and performance requirements of portable devices

such as cell phones and MP3 and portable DVD players.

♦ 1.8V to 3.6V Single-Supply Operation

♦ 30mW Stereo Headphone Output Power with

1.8V Supply

♦ DirectDrive Outputs Eliminate DC-Blocking

The MAX9850 uses Maxim’s DirectDrive headphone

technology that produces a ground-biased analog

audio output from a single supply, which allows for dri-

ving the headphones directly from the amplifier outputs

without large DC-blocking capacitors. This feature

saves board space, provides higher click/pop suppres-

sion, and improves low-frequency (bass) response. The

architecture does not require the headphone jack to be

biased to a DC voltage and thus allows for a conven-

tional, grounded chassis design.

Capacitors

♦ 91dB PSRR at 1kHz

♦ Any Master Clock Up to 40MHz

♦ Flexible I S-Compatible Digital Audio Interface

♦ I C Headphone Volume and Mute Control

♦ Stereo Line Inputs and Outputs

♦ Clickless/Popless Operation

The MAX9850’s flexible clocking circuitry utilizes any

available system clock up to 40MHz, eliminating the

need for an external PLL and multiple crystal oscillators.

The DAC supports a wide range of sample rates from

8kHz to 48kHz in both master and slave modes, making

the MAX9850 the easiest to use and most versatile audio

DAC available. It can also be operated like traditional

synchronous DACs, at any integer-oversampling ratio.

♦ 2-Wire (I C)-Compatible Control Interface

♦ Available in 28-Pin Thin QFN Package
