PCM1850PJT TI Audio ADC | 32-TQFP (7x7) | 24-Bit, 96kHz Stereo

Product Overview

The PCM1850PJT is a high-performance, single-chip stereo audio analog-to-digital converter (ADC) from Texas Instruments. It features a 24-bit delta-sigma modulator with 96 kHz sampling rate, providing excellent dynamic range and low distortion. The device integrates a stereo audio ADC, anti-aliasing filters, and a flexible serial audio interface. Housed in a compact 32-TQFP (7x7 mm) package, it is ideal for space-constrained applications requiring high-quality audio conversion.
