PCM1865DBT TI Audio ADC | 30-TSSOP | 4-Ch, 192kHz, 110dB SNR

Product Overview

The PCM1865DBT is a high-performance, low-power stereo audio analog-to-digital converter (ADC) from Texas Instruments. It supports up to 4 channels of simultaneous sampling with a dynamic range of 110 dB and a sampling rate up to 192 kHz. The device is housed in a compact 30-pin TSSOP package, making it ideal for space-constrained applications. It features a flexible serial audio interface (I2S, left-justified, right-justified, TDM) and supports both single-ended and differential inputs. The PCM1865DBT is designed for professional audio, automotive, and industrial applications requiring high-fidelity audio capture.
