AKM Semiconductor, Inc. Data Acquisition - Data Acquisition - ADCs/DACs - Special Purpose - AK5703EN AK5703EN

The AK5703EN is a 4-channel, 24-bit analog-to-digital converter (ADC) designed for consumer microphone array applications. It features programmable microphone amplifiers with gain settings ranging from +36dB to 0dB, and an Automatic Level Control (ALC) circuit. The device supports both full-differential and single-ended inputs, achieving a dynamic range of 83dB at a +30dB microphone gain setting. The ADC operates with a sampling frequency range of 8kHz to 48kHz in both master and slave modes, and it includes a digital high-pass filter for DC-offset cancellation. The AK5703EN is packaged in a compact 28-pin QFN format, making it suitable for space-constrained designs. It operates within a temperature range of -30¬8C to +85¬8C and requires a power supply of 2.4V to 3.6V for AVDD and 1.6V to 1.98V for DVDD. The power consumption is approximately 9.0mA in external slave mode. This product is ideal for applications requiring high-quality audio data acquisition with flexible microphone interfacing.
