ADS5421Y/R

Analog To Digital Converters (ADC) Overview

The ADS5421Y/R is a high-performance, single-channel 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a sampling rate of 40 MSPS and utilizes a pipeline architecture. The device accepts differential analog inputs and features a parallel digital interface for data output. It requires an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply between 3 V and 5 V. Key performance metrics include a signal-to-noise ratio (SNR) of 76 dB, an effective number of bits (ENOB) of 12.1 bits, and a power dissipation of approximately 900 mW. The component is housed in a 64-lead LQFP package and supports an operating temperature range from -40°C to +85°C.
