What this codec brings to the audio chain
The Analog Devices MAX9867ETJ+G3U is a low-power stereo audio codec built around an 18-bit sigma-delta converter core. It integrates two ADCs and two DACs, giving you a full duplex stereo path for line-level or microphone inputs and headphone/line outputs. The digital interface runs over I²C or a serial port, so it fits neatly into portable audio gear, VoIP terminals, intercoms, and industrial voice-annunciation boards where the supply rails sit between 1.65 V and 1.95 V.
Dynamic range — the spec that sets the noise floor
The ADC path delivers 85 dB dynamic range; the DAC path hits 90 dB.
Temperature grade and environment
Rated for -40°C to 85°C operation, the MAX9867ETJ+G3U covers industrial-temperature environments.
