Overview
The AD9235BRUZ-40 is a 12-bit, high-performance analog-to-digital converter (ADC) produced by Analog Devices Inc. This component operates from a single 3 V power supply and is available in a 28-lead Thin Shrink Small Outline Package (TSSOP). The AD9235 family includes models that can sample at rates of 20, 40, and 65 million samples per second (MSPS), making it versatile for various applications. It features a multistage differential pipelined architecture with output error correction logic, ensuring 12-bit accuracy and no missing codes over the full operating temperature range of -40°C to +85°C.
