ADC12040CIVYX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12040CIVYX/NOPB is a monolithic CMOS analog-to-digital converter manufactured by Texas Instruments. It provides 12-bit resolution with a sampling rate of 40 MSPS using a pipeline architecture. The device operates on a single +5V supply, consuming 340 mW at full speed, and supports digital logic voltages from 2.35 V to 5.25 V. Key electrical specifications include a Signal-to-Noise Ratio (SNR) of 70 dB, an Effective Number of Bits (ENOB) of 11.2 bits, and a Differential Nonlinearity (DNL) of +/- 0.4 LSB. It features differential inputs, parallel output data format, and an internal sample-and-hold circuit. The component is housed in a 32-TQFP package and functions within an industrial temperature range of -40°C to +85°C.
