ADC12020CIVYX

Analog To Digital Converters (ADC) Overview

The ADC12020CIVYX is a monolithic CMOS analog-to-digital converter (ADC) from Texas Instruments that converts analog input signals into 12-bit digital data at a sampling rate of 20MSPS. It features a differential pipeline architecture with digital error correction and an on-chip sample-and-hold circuit to minimize die size and power consumption while maintaining dynamic performance. The device operates on a single +5V supply, consuming 185mW at full speed including reference current, which drops to 40mW in shutdown mode. It includes a buffered high-impedance single-ended reference input converted internally to a differential reference. The component supports TTL/CMOS compatible I/O and functions within an industrial temperature range of -40°C to +85°C.
