The MAX9860ETG+T is an ultra low power, 16bit mono audio voice codec with programmable digital filters in 24 pin TQFN package. This voice band audio codec is designed to provide 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 in to 32ohm earpiece while operating from single 1.8V power supply. Very low power consumption makes it an ideal choice for battery powered applications. The flexible clocking circuitry utilizes common system clock frequencies ranging from 10MHz to 60MHz by eliminating need for an external PLL and multiple crystal oscillators. Both ADC and DAC support sample rates of 8KHz to 48KHz in either synchronous or asynchronous operation. Serial DAC and ADC data is transferred over a flexible digital I2S compatible interface (also supports TDM mode). The mode settings, volume control and shutdown are programmed through 2-wire, I2C interface.
