Overview
The AD9244BST-65 from Analog Devices Inc. is a high-performance, monolithic 14-bit analog-to-digital converter (ADC) designed for high-speed data acquisition applications. This ADC operates at sampling rates of up to 65 MSPS and features a multistage differential pipelined architecture with output error correction logic, ensuring 14-bit accuracy and guaranteeing no missing codes over the full operating temperature range. The device includes an on-chip sample-and-hold amplifier and a programmable voltage reference, which can also be driven externally. It is fabricated on an advanced CMOS process and is available in a 48-lead LQFP package, suitable for operation over the industrial temperature range of –40°C to +85°C.
