Product Overview

The MAX9867ETJ+ is an ultra low power stereo audio codec in 32 pin TQFN package. The device has stereo differential microphone inputs that can be connected to either analogue or digital microphones. The single ended line inputs with configurable preamplifier can be sent to ADC for record or routed directly to headphone amplifier for playback. An auxiliary 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 32ohm headphones. Comprehensive click and pop circuitry suppresses audible clicks and pops during volume changes and start-up or shutdown. Utilizing Maxim's 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.
  • Supply voltage range from 1.65V to 1.95V (PVDD, DVDD, AVDD) and 1.65V to 3.6V (DVDDIO)
  • Operating temperature range from -40°C to 85°C
  • I2S/TDM compatible digital audio bus
  • Integrates auxiliary battery measurement ADC and capacitorless headphone amps
  • 6.7mW playback power consumption
  • 90dB stereo DAC, 8KHz <= fS <= 48KHz and 85dB stereo ADC, 8KHz <= fS <= 48KHz
  • Stereo digital microphone input support stereo analogue differential microphone inputs
  • Gain error of 1% and PSRR (DAC) of 78dB f = 217Hz, VRIPPLE = 100mVP-P, AVVOL = 0dB
  • Voiceband filter with stopband attenuation greater than 70dB
  • Shutdown supply current of 1µA (analogue (AVDD + PVDD)) at TA = +25°C
