ADAU1772BCPZ

The Analog Devices ADAU1772BCPZ is a versatile low-power audio codec designed for applications requiring high-quality audio processing. It integrates four analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs), all operating at 24-bit resolution.

This codec boasts a programmable audio processing engine capable of 192 kHz processing, including biquad filters, limiters, and volume controls. It achieves a signal-to-noise ratio (SNR) of 102 dB for the ADC path and 107 dB for the DAC path, with a low analog-to-analog latency of 38 μs. The device supports sample rates from 8 kHz to 192 kHz and features full-duplex asynchronous sample rate converters (ASRCs).

Connectivity is managed via I2C and SPI control interfaces, with self-boot capability from an I2C EEPROM. The ADAU1772BCPZ operates on analog and digital I/O voltages from 1.8 V to 3.3 V, with its DSP core running at 1.1 V to 1.8 V. Its low power consumption, typically 15 mW for noise-cancelling solutions, makes it suitable for battery-powered devices.

Packaged in a 40-LFCSP-WQ (6x6) format, the ADAU1772BCPZ is designed for surface mounting. Its applications include noise-cancelling handsets, headsets, headphones, Bluetooth ANC devices, personal navigation devices, and digital cameras.
