ADAU1461WBCPZ-R7

Overview

The ADAU1461WBCPZ-R7 is a low-power stereo audio codec with an integrated SigmaDSP processor. It features 24-bit stereo ADCs and DACs supporting sampling rates from 8 kHz to 96 kHz. The device includes six analog input pins, flexible mixers, and five output drivers (two differential, three single-ended). It operates on a 3.3 V analog supply and digital I/O, consuming 17 mW during record and 18 mW during playback at 48 kHz. An integrated PLL supports input clocks between 8 MHz and 27 MHz. The component is housed in a 32-lead LFCSP package and operates within a temperature range of -40°C to +105°C.
