Analog Devices AD7641 Datasheet
The document describes the AD7641, a fully differential analog-to-digital converter (ADC) with 18-bit resolution and no missing codes. It operates from a single 2.5 V power supply and offers two throughput modes: Warp mode at 2 MSPS and Normal mode at 1.5 MSPS.
The device includes an internal low-drift reference, error correction circuits, and both serial (SPI/QSPI/Microwire/DSP compatible) and parallel system interface ports. It is designed for applications such as medical instruments, high dynamic data acquisition, instrumentation, spectrum analysis, and automated test equipment (ATE).
