Description

AUDIO CODEC 24BIT 192KSPS LFCSP-40

The ADAU1372 is a codec with four inputs and two outputs, which incorporates asynchronous sample rate converters. Optimized for low latency and low power, the ADAU1372 is ideal for headsets, handsets, and headphones. The ADAU1372 has built-in program- mable gain amplifiers (PGAs); thus, with the addition of just a few passive components and a crystal, the ADAU1372 provides a solution for headset audio needs, microphone preamplifiers, ADCs, DACs, headphone amplifiers, and serial ports for connections to an external DSP. Note that throughout this data sheet, multifunction pins, such as SCL/SCLK, are referred to either by the entire pin name or by a single function of the pin, for example, SCLK, when only that function is relevant.
