Overview
The AD9245BCPZRL7-80, produced by Analog Devices Inc., is a high-performance, monolithic 14-bit analog-to-digital converter (ADC) designed for a wide range of applications. It operates from a single 3 V power supply and features a separate digital output driver supply to accommodate 2.5 V and 3.3 V logic families. The AD9245 uses a multistage differential pipelined architecture with output error correction logic, ensuring 14-bit accuracy and no missing codes over the full operating temperature range of –40°C to +85°C.
