ADS42B49IRGC25

Analog To Digital Converters (ADC) Overview

The ADS42B49IRGC25 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 250 MSPS and utilizes a pipeline architecture. The device features differential analog inputs and supports both parallel CMOS and LVDS digital output interfaces. It functions on a single 1.8 V supply for both analog and digital domains. Key performance metrics include a signal-to-noise ratio (SNR) of approximately 71 dB and an effective number of bits (ENOB) of roughly 11.5 bits. The component is housed in a compact VQFN-64 package and is rated for industrial operating temperatures ranging from -40°C to +85°C.
