ADS42JB69IRGCT

Analog To Digital Converters (ADC) Overview

The ADS42JB69IRGCT is a dual-channel, 16-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 250 MS/s with a pipeline architecture. The device features differential inputs and supports both serial CMOS and LVDS digital interfaces. It functions on a single 1.8 V supply for both analog and digital sections. Key performance metrics include a full power bandwidth of 900 MHz, an SNR of 75.9 dB, and an ENOB of 12.1 bits. DNL is specified at 0.6 LSB. It is housed in a 64-pin VQFN package and operates within a temperature range of -40°C to +85°C.
