General Description
The MAX9880A is a high-performance, stereo audio
codec designed for portable consumer applications
such as smartphones and tablets. Operating from a sin-
gle 1.8V supply to ensure low-power consumption, the
MAX9880A offers a variety of input and output configu-
rations for design flexibility. The MAX9880A can be
combined with an audio subsystem, such as the
MAX9877 or MAX9879, for a complete audio solution
for portable applications.
The MAX9880A’s stereo differential microphone inputs
can support either analog or digital microphones. A
stereo single-ended line input, with a configurable pre-
amplifier, can either be recorded by the ADC or routed
directly to the headphone or line output amplifiers. The
stereo headphone amplifiers can be configured as dif-
ferential, single ended, or capacitorless. The stereo line
outputs have dedicated level adjustment.
There are two digital audio interfaces. The primary
interface is intended for voiceband applications, while
the secondary interface can be used for high perfor-
mance stereo audio data. Two digital input streams can
be processed simultaneously and both digital inter-
faces support TDM and I2S data formats.
The flexible clocking circuitry utilizes any available
10MHz to 60MHz system clock, eliminating the need for
an external PLL and multiple crystal oscillators. Both
the ADC and DAC can be operated synchronously or
asynchronously in master or slave mode. The ADC can
be operated from 8kHz to 48kHz sample rates, while
the DAC can be operated up to 96kHz.
The MAX9880A prevents click and pop during volume
changes and during power-up and power-down. Audio
quality is further enhanced with user-configurable digital
filters for voice and audio data. Voiceband filters pro-
vide extra attenuation at the GSM packet frequency and
greater than 70dB stopband attenuation at fS/2. An I2C
or SPI serial interface provides control for volume lev-
els, signal mixing, and general operating modes.
The MAX9880A is available in space-saving, 48-bump,
2.7mm x 3.5mm, 0.4mm-pitch WLP and 48-pin, 6mm x
6mm TQFN packages.
