ADAU1761BCPZ stereo audio codec
The ADAU1761BCPZ is a low-power, stereo audio codec with integrated SigmaDSP digital audio processing from Analog Devices, housed in a compact 32-pin LFCSP package. It features 24-bit stereo ADCs and DACs supporting sample rates from 8 kHz to 96 kHz, with an integrated PLL that accepts input clocks from 8 MHz to 27 MHz. The device operates from 1.8 V to 3.65 V analog and digital supplies, delivering 14 mW total power consumption for stereo 48 kHz record and playback, making it ideal for battery-powered and space-constrained audio systems.
Key features include a 28-/56-bit SigmaDSP digital audio processor running at 50 MIPS, fully programmable via the SigmaStudio graphical tool for custom audio processing algorithms. The stereo audio ADC and DAC achieve >98 dB SNR with digital volume control and flexible analog input/output mixers. The device provides six analog input pins configurable for single-ended or differential inputs, stereo digital microphone input, and multiple analog outputs including two differential stereo outputs, two single-ended stereo outputs, and a mono headphone output driver. Integrated analog automatic level control (ALC), microphone bias reference voltage, and comprehensive power management registers enable efficient operation in portable applications.
Alternative audio codec Models
● ADAU1761BCPZ-RL: A tape-and-reel packaged version of the ADAU1761BCPZ with identical audio codec and SigmaDSP functionality for high-volume manufacturing.
● ADAU1361BCPZ: A pin-compatible 24-bit stereo audio codec with similar 96 kHz performance but without the SigmaDSP digital audio processor, offering a cost-effective solution for applications that don't require programmable DSP.
● ADAU1961: A stereo, low-power 96 kHz 24-bit audio codec with integrated PLL from the same product family, providing alternative packaging and performance options for different system requirements.
● AK4376AECB: A 32-bit stereo DAC with integrated headphone amplifier from AKM, offering high-resolution audio playback for portable audio players and USB DAC adapters.
