Overview
The AD9238BSTZRL-40 is a dual, 3 V, 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component features dual high-performance sample-and-hold amplifiers (SHAs) and an integrated voltage reference. It uses a multistage differential pipelined architecture with output error correction logic to ensure 12-bit accuracy and guarantee no missing codes over the full operating temperature range. The AD9238 is available in a 64-lead LQFP package and is specified over the industrial temperature range of -40°C to +85°C.
