AD7687BRMZRL7

AD7687 is a 16bit, charge redistribution, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply. It contains a low power, high speed, 16bit sampling ADC with no missing codes, an internal conversion clock, and a versatile serial interface port. The device also contains a low noise, wide bandwidth, short aperture delay track-and-hold circuit. The SPI-compatible serial interface also features the ability to daisy-chain several ADCs on a single 3-wire bus and provides an optional BUSY indicator by means of the SDI pin. Typical application includes battery-powered equipment, data acquisition, instrumentation, medical instruments and process control.
