●Product Details
●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 programmable 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.
