PCM1851PJTG4 Description

The PCM1851PJTG4 is a high-performance, low-cost, single-chip stereo analog- to-digital converter with a single-ended analog front end that consists of a 6-stereo-input multiplexer and wide-range PGA. The PCM1851PJTG4 also includes a delta-sigma modulator with 64-times oversampling, a digital decimation filter and a low-cut filter that removes the dc component of the input signal.
