The AD7946BRMZ is a charge redistribution successive approximation Analog-to-digital Converter (ADC) that operates from a single 5V power supply VDD. It contains a low power high speed 14-bit sampling ADC with no missing codes, an internal conversion clock and a versatile serial 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 0V 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. The SPI-compatible serial interface also features the ability, using the SDI input, to daisy-chain several ADCs on a single, 3-wire bus or it provides an optional BUSY indicator.
