Overview
The AD9203ARU is a monolithic, low-power, single-supply, 10-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. It operates at a sampling rate of 40 MSPS and is designed for high-speed, low-power applications. The ADC uses a multistage differential pipeline architecture, ensuring no missing codes over the full operating temperature range. It features an on-chip voltage reference and can also use an external reference to meet specific DC accuracy and temperature drift requirements. The device is fabricated on an advanced CMOS process and is available in a 28-lead thin shrink small outline package (TSSOP), suitable for industrial temperature ranges from −40°C to +85°C.
