GENERAL DESCRIPTION

The AD7694 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

5.25 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 CNV rising 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 AD7694 is housed in an 8-lead MSOP package with an

operating temperature specified from −40°C to +85°C.
