Overview
The PCM1863DBTR, produced by Texas Instruments, is a 110dB 2-Channel Software-Controlled Audio Analog-to-Digital Converter (ADC) with a universal front end. This device is part of the PCM186x family, which includes the PCM1860, PCM1861, PCM1862, PCM1864, and PCM1865. The PCM1863 is designed to integrate multiple audio functions, making it easier to comply with European Ecodesign legislation while enabling high-performance end products at reduced costs. It operates on a single 3.3-V power supply and features an integrated programmable gain amplifier (PGA) in a compact TSSOP (DBT) package with 30 pins.
