Overview
The AD9203ARURL7 is a 10-bit, 40 MSPS (Mega Samples Per Second) analog-to-digital converter (ADC) produced by Analog Devices Inc. This monolithic, single-supply ADC is designed for low power consumption and high performance. It operates on a supply range from 2.7 V to 3.6 V and is housed in a 28-Lead Thin Shrink Small Outline (TSSOP) package. The AD9203 features a multistage differential pipeline architecture, ensuring no missing codes over the full operating temperature range of -40°C to +85°C. It includes an on-chip voltage reference and supports both differential and single-ended input configurations with an adjustable input range of 1 V to 2 V p-p.
