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.
The AD7699 uses a simple serial port interface (SPI) for writing
to the configuration register and receiving conversion results.
The SPI interface uses a separate supply, VIO, which is set to the
host logic level. Power dissipation scales with throughput.
The AD7699 is housed in a tiny 20-lead LFCSP with operation
specified from −40°C to +85°C.
