AD7694ARMZRL7

AD7694 is a 16bit, charge redistribution, successive approximation, PulSAR analogue-to-digital converter (ADC) that operates from a single power supply, VDD, between 2.7V to 5.25V. The part also contains a low noise, wide bandwidth, short aperture delay track-and-hold circuit. On the CNV rising edge, it samples an analogue input, IN+, between 0V to REF with respect to a ground sense, IN-. The reference voltage, REF, is applied externally and can be set upto the supply voltage. It is used in applications such as battery-powered equipment, data acquisition, instrumentation, medical instruments, process control.
