AK5734 - 4-Channel Differential Audio ADC

Description

The AK5734 is a 4-channel audio ADC with an integrated SAR ADC, enabling robust error detection.

The error detection function monitors the connection status of the line and microphone inputs.

The AK5734 includes mic PGAs (pre-gain amplifiers) and programmable microphone bias.

[AK5734] AK5734 4-Channel Differential Audio ADC with Diagnostics 1. General Description The AK5734 is a 4-channel audio ADC with an integrated SAR ADC, enabling robust error detection. The error detection function monitors the connection status of the line and microphone inputs. The AK5734 includes mic PGAs (pre-gain amplifiers) and programmable microphone bias. These functions make it ideal for microphone array applications such as automotive ANC (Active Noise Cancelation). The digital audio interface supports I2S, multi-slot TDM, and left-justified formats, making it easy to connect to your DSP of choice. 2. Features 1. Audio ADC - 4-Channel Audio ADC - Full-differential Input and Single-ended Input - PGA for Microphone: 0dB or 6dB - 20dB (1dB step) - Input Voltage: 2.
