ADS42B49IRGCR

Analog To Digital Converters (ADC) Overview

The ADS42B49IRGCR is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 250 MSPS with a pipeline architecture. The device accepts differential inputs and provides parallel digital outputs. It requires an analog supply voltage ranging from 3.15 V to 3.6 V and a digital supply voltage between 1.7 V and 1.9 V. Key performance metrics include a signal-to-noise ratio (SNR) of 73 dB, an effective number of bits (ENOB) of 11.3 bits, and a power dissipation of approximately 1.15 W. It functions within a temperature range of -40°C to +85°C and is housed in a VQFN-64 package.
