GENERAL DESCRIPTION
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.
The AD7683 is housed in an 8-lead MSOP or an 8-lead QFN
(LFCSP) package, with an operating temperature specified from
40°C to +85°C.
