AD9203ARURL7

Analog To Digital Converters (ADC) Overview

The AD9203ARURL7 is a monolithic, low-power, single-supply 10-bit analog-to-digital converter manufactured by Analog Devices Inc. It operates at a maximum sampling rate of 40 MSPS with a power dissipation of 74 mW on a 3 V supply. The device features a multistage differential pipeline architecture and guarantees no missing codes across the full operating temperature range. It includes an onboard programmable voltage reference that can be adjusted between 0.5 V and 1 V, or bypassed for external reference operation. The input span is adjustable from 1 V to 2 V peak-to-peak in either differential or single-ended configurations. Power consumption can be further reduced via an external resistor at lower sample rates.
