The MAX9860 is a low-power, voiceband, mono audio
codec designed to provide a complete audio solution
for wireless voice headsets and other mono voice audio
devices. Using an on-chip bridge-tied load mono head-
phone amplifier, the MAX9860 can output 30mW into a
32Ω earpiece while operating from a single 1.8V power
supply. Very low power consumption makes it an ideal
choice for battery-powered applications.
The MAX9860’s flexible clocking circuitry utilizes com-
mon system clock frequencies ranging from 10MHz to
60MHz, eliminating the need for an external PLL and
multiple crystal oscillators. Both the ADC and DAC sup-
port sample rates of 8kHz to 48kHz in either synchro-
nous or asynchronous operation. Both master and slave
timing modes are supported.
Two differential microphone inputs are available with a
user-programmable preamplifier and programmable
gain amplifier. Automatic gain control with selectable
attack/release times and signal threshold allows maxi-
mum dynamic range. A noise gate with selectable
threshold provides a means to quiet the channel when
no signal is present. Both the DAC and ADC digital filters
provide full attenuation for out-of-band signals as well as
a 5th order GSM-compliant digital highpass filter. A digi-
tal side tone mixer provides loopback of the micro-
phones/ADC signal to the DAC/headphone output.
Serial DAC and ADC data is transferred over a flexible
digital I
mode. Mode settings, volume control, and shutdown are
programmed through a 2-wire, I
The MAX9860 is fully specified over the -40°C to +85°C
extended temperature range and is available in a low-
profile, 4mm x 4mm, 24-pin thin QFN package.
