ADC14L020CIVY/NOPB

Analog To Digital Converters (ADC) Overview

The ADC14L020CIVY/NOPB is a 14-bit, 20 MSPS analog-to-digital converter manufactured by Texas Instruments. It utilizes a pipeline architecture with differential input and parallel interface. The device operates on a single 3.3 V analog supply and supports digital I/O voltages between 2.4 V and 3.6 V. Key performance metrics include a signal-to-noise ratio of 74 dB, an effective number of bits (ENOB) of 11.9, and a power dissipation of 235 mW. It is housed in a 32-lead LQFP package and functions within an industrial temperature range of -40°C to +85°C.
