The ADAU1977WBCPZ is a quad analog-to-digital converter (ADC) designed for audio applications. It operates with a 24-bit resolution and supports sampling rates from 8 kHz to 192 kHz. The device includes four differential inputs capable of handling 10 V rms signals, making it suitable for direct connection to electret microphones. It provides programmable microphone bias voltage from 5 V to 9 V.
The ADC achieves a dynamic range of 109 dB and a total harmonic distortion plus noise (THD+N) of -95 dB. It features an on-chip phase-locked loop (PLL) for master clock generation and supports both I²C and SPI control interfaces. The device includes digital volume control with autoramp function and software-controllable clickless mute. It can operate in master or slave mode.
The ADAU1977WBCPZ is qualified for automotive applications and is housed in a 40-lead LFCSP package (6x6 mm) with surface mount mounting. It operates from a single 3.3 V supply and over a temperature range of -40°C to 105°C.
