Overview
The AD9245BCPZRL7-40, produced by Analog Devices Inc., is a high-performance, 14-bit analog-to-digital converter (ADC) designed for a wide range of applications. This monolithic ADC operates from a single 3 V power supply and features a high-performance sample-and-hold amplifier (SHA) and an on-chip voltage reference. The AD9245 uses a multistage differential pipelined architecture with output error correction logic to ensure 14-bit accuracy and guarantee no missing codes over the full operating temperature range of –40°C to +85°C.
