PCM1861DBT

ADCs/DACs - Special Purpose Overview

The PCM1861DBT is a stereo audio analog-to-digital converter (ADC) from Texas Instruments, part of the PCM186x family. It features a universal front end supporting both differential and single-ended inputs with programmable gain amplifiers. The device delivers high performance with a signal-to-noise ratio of 110 dB and supports sampling rates up to 192 kHz at 24-bit resolution. It utilizes hardware control for configuration and operates within a temperature range of -40°C to +125°C. The component is housed in a TSSOP-30 package designed for surface-mount installation.
