PCM1870YZFR TI Audio ADC | 24-DSBGA | 96kHz, 24-Bit, Low Power

Product Overview

The PCM1870YZFR is a low-power, stereo audio analog-to-digital converter (ADC) from Texas Instruments. It features a 24-bit delta-sigma modulator with 96 kHz sampling rate, providing high-resolution audio conversion for portable and embedded applications. The device operates from a 1.8V analog supply and a 1.65V to 3.6V digital I/O supply, making it suitable for battery-powered devices. It includes a programmable gain amplifier (PGA) with 0 dB to 24 dB gain range and supports both I2S and left-justified audio data formats. The PCM1870YZFR is available in a compact 24-ball DSBGA package (0.4 mm pitch) for space-constrained designs.
