Product details
The ADAU7002ACBZ-R7 is a high-performance, stereo PDM-to-I2S/TDM digital converter engineered by Analog Devices (ADI). In the modern audio signal chain, this IC acts as a crucial hardware bridge between digital MEMS microphones and system processors (DSPs or Application Processors).
Product Introduction
The ADAU7002 is a specialized Digital-to-Digital Interface IC. It accepts a stereo PDM (Pulse Density Modulation) bitstream-the industry standard for digital microphones-and converts it into a decimated, 24-bit I2S or TDM format. Its "standalone" architecture allows it to operate without I2C/SPI software registers, providing a transparent, low-latency audio pipeline for rapid hardware integration.
Product Advantages
- Zero-Firmware Integration: Hardware-configurable pins eliminate the need for complex driver development.
- Unmatched Signal Clarity: A 120 dB SNR ensures the digital output from premium mics is preserved without degradation.
- Ultra-Compact Footprint: The WLCSP packaging is perfect for high-density PCBs in TWS earbuds and smart glasses.
- Extreme Efficiency: Optimized for "Always-on" voice wake-up applications with negligible current draw.
Product Features
- Supports 2 channels of PDM audio on a single input line.
- Selectable output formats: I2S, Left-Justified, and multi-channel TDM.
- Fixed 64× oversampling ratio with a high-performance linear phase digital filter.
- Supports Master or Slave mode clocking configurations.
- Wide sampling rate support from 8 kHz up to 192 kHz.
