GENERAL DESCRIPTION
The AD7699 is an 8-channel, 16-bit, charge redistribution successive approximation register (SAR) analog-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 16-bit 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 4.096 V 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.
