PCM1803ADBRG4

ADCs/DACs - Special Purpose Overview

The PCM1803ADBRG4 is a stereo audio analog-to-digital converter manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 96 kHz. The device utilizes a Delta-Sigma architecture with single-ended analog inputs and communicates via a serial interface. It operates within an analog supply voltage range of 4.5 V to 5.5 V and a digital supply range of 2.7 V to 3.6 V. Packaged in a 20-pin SSOP, it functions across a temperature range of -40°C to +85°C.
