Description

General part information

PCM1821 Series

The PCM182x is a high-performance, Burr-Brown™ audio analog-to-digital converter (ADC) that supports simultaneous sampling of up to two analog channels. The device supports differential line and microphone inputs with a 2-VRMSfull-scale signal. The device integrates a phase-locked loop (PLL), a DC removal high-pass filter (HPF), and supports sample rates up to 192 kHz. The device supports time-division multiplexing (TDM) or I2S audio formats, selectable with the hardware pin level. Additionally, the PCM182x supports master and slave mode selection for the audio bus interface operation. These integrated high-performance features, along with the ability to be powered from a single supply of 3.3 V, make the device an excellent choice for cost-sensitive, space-constrained audio systems in far-field microphone recording applications.

The PCM182x is specified from –40°C to +125°C, and is offered in a 20-pin WQFN package.
