Mono audio codec for voice-grade signal chains
The MAX9860ETG+ from Analog Devices is a mono audio codec built around a 16-bit sigma-delta converter core. It integrates two ADCs and one DAC on a single die, making it a compact front-end for voice-band processing in portable or embedded audio systems. The serial data interface keeps pin count low on the 24-TQFN (4x4 mm) package, and the exposed pad aids thermal transfer in the surface-mount assembly.
Dynamic range and supply — what they mean for the audio path
The ADC path delivers 81 dB dynamic range typ; the DAC side hits 90 dB typ. That spread tells you the playback side has a quieter noise floor than the capture side — fine for voice communication where the microphone path is the bottleneck anyway. Both analog and digital supplies share a 1.7V to 1.9V range, so a single 1.8V rail can feed the whole codec without a separate regulator for the analog core. The industrial temperature grade (-40°C to 85°C) suits outdoor telecom gear, portable instrumentation, or any enclosure that sees seasonal swings.
Active lifecycle and compliance
The MAX9860ETG+ carries an active product status with ROHS3 compliance.
