Product Summary

The AD7683ARM is a 16-bit, charge redistribution, successive approximation, PulSAR analog-to-digital converter (ADC) that operates from a single power supply, VDD, between 2.7 V to 5.5 V. It contains a low power, high speed, 16-bit sampling ADC with no missing codes (B grade), an internal conversion clock, and a serial, SPI-compatible interface port. The part also contains a low noise, wide bandwidth, short aperture delay, track-and-hold circuit. On the CS falling edge, the AD7683ARM samples an analog input, +IN, between 0 V to REF with respect to a ground sense, –IN. The reference voltage, REF, is applied externally and can be set up to the supply voltage. Its power scales linearly with throughput. The applications of the AD7683ARM include Battery-powered equipment, Data acquisition, Instrumentation, Medical instruments, Process control.
