AD7699BCPZ

AD7699 is an 8-channel, 16bit, charge redistribution successive approximation register (SAR) analogue-to-digital converter (ADC) that operates from a single power supply VDD. The AD7699 contains all components for use in a multichannel, low power data acquisition system, including a true 16bit SAR ADC with no missing codes, an 8-channel low crosstalk multiplexer useful for configuring the inputs as single-ended (with or without ground sense), differential or bipolar, an internal 4.096V low drift reference and buffer, a temperature sensor, a selectable one-pole filter, and a sequencer that is useful when channels are continuously scanned in order. Typical applications include battery-powered equipment, medical instruments: ECG/EKG, mobile communications: GPS, personal digital assistants, power line monitoring, data acquisition Seismic data acquisition systems, instrumentation and process control.
