AD7683ARMZRL7

模数转换器 - ADC 100 kSPS 16-BIT

16-Bit, 100 kSPS, Single-Ended  PulSAR ADC in MSOP/QFN

GENERAL DESCRIPTION AD7683ARMZRL7

The AD7683 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 and 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, it 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.
