Overview
The AD9244BSTZ-40, produced by Analog Devices Inc., is a high-performance, 14-bit analog-to-digital converter (ADC) designed for data acquisition applications. This monolithic device operates on a single 5 V supply and features an on-chip sample and hold amplifier and voltage reference. The AD9244 uses a multi-stage differential pipelined architecture with output error correction logic to achieve 14-bit accuracy at data rates of up to 40 MSPS. It guarantees no missing codes over the full operating temperature range of -40°C to +85°C and is packaged in a 48-pin surface mount plastic package (48-LQFP).
