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 headphone 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 common system clock frequencies ranging from 10MHz to 60MHz, eliminating the need for an external PLL and multiple crystal oscillators. Both the ADC and DAC support sample rates of 8kHz to 48kHz in either synchronous 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 maximum 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 digital side tone mixer provides loopback of the microphones/ADC signal to the DAC/headphone output.

Serial DAC and ADC data is transferred over a flexible digital I²S-compatible interface that also supports TDM mode. Mode settings, volume control, and shutdown are programmed through a 2-wire, I²C-compatible interface.

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.

Product Detail

The MAX9860 evaluation kit (EV kit) consists of a MAX9860 evaluation board and software. The EV kit is a fully assembled and tested circuit board that evaluates the MAX9860 low-power, voiceband, mono audio codec. The EV kit is designed to send and receive digital audio data in the Sony/Philips digital interface (S/PDIF) format and can be optionally configured to communicate using generic digital audio or I²S-compatible signals. The EV kit provides fiber optic receiving and transmitting modules for digital audio input and output.

The EV kit includes Windows® 2000-, Windows XP®-, and Windows Vista®-compatible software that provides a graphical user interface (GUI) for exercising the features of the MAX9860. The EV kit is connected to a PC through a USB A-to-B cable.
