PCM1804DB TI Audio ADC | 28-SSOP | 24-Bit, 96kHz, 111dB SNR

Product Overview

The PCM1804DB is a high-performance, single-chip, stereo analog-to-digital converter (ADC) from Texas Instruments. It supports 24-bit resolution and sampling rates up to 96 kHz, delivering a dynamic range of 111 dB (A-weighted) and a signal-to-noise ratio (SNR) of 111 dB. The device integrates a delta-sigma modulator with a digital decimation filter, providing excellent audio quality for professional and consumer applications. Housed in a compact 28-pin SSOP package, it operates from a single 5V supply and features a serial audio interface (I2S) for easy connection to DSPs or microcontrollers.
