The MAX9867 is an ultra-low power stereo audio codec

designed for portable consumer devices such as

mobile phones and portable gaming consoles.

The device features stereo differential microphone inputs

that can be connected to either analog or digital micro-

phones. The single-ended line inputs, with configurable

preamplifier, can be sent to the ADC for record or routed

directly to the headphone amplifier for playback. An aux-

iliary ADC path can be used to track any DC voltage.

The stereo headphone amplifiers support differential,

single-ended, and capacitorless output configurations.

Using the capacitorless output configuration, the

device can output 10mW into 32Ω headphones.

Comprehensive click-and-pop circuitry suppresses

audible clicks and pops during volume changes and

startup or shutdown.

Utilizing Maxim’s proprietary digital circuitry, the device

can accept any available 10MHz to 60MHz system

clock. This architecture eliminates the need for an

external PLL and multiple crystal oscillators. The stereo

ADC and DAC paths provide user-configurable voice-

band or audioband digital filters. Voiceband filters pro-

vide extra attenuation at the GSM packet frequency

and greater than 70dB stopband attenuation at f

The MAX9867 operates from a single 1.8V supply, and

supports a 1.65V to 3.6V logic level. An I

al interface provides control for volume levels, signal

mixing, and general operating modes.

The MAX9867 is available in a tiny 2.2mm x 2.7mm,

0.4mm-ball-pitch, WLP package. A 32-pin 5mm x 5mm

TQFN package is also available.
