GENERAL DESCRIPTION
This data sheet describes the evaluation board for testing the
AD7992 device. This device is a 12-bit, low power, successive
approximation analog-to-digital converter (ADC) with an
I²C-compatible interface. The part operates from a single 2.7 V
to 5.5 V power supply and features a 2 μs conversion time.
The AD7992 contains a 2-channel multiplexer and track-and-
hold amplifier that can handle input frequencies of up to 11 MHz.
Full details on this device are provided in the AD7992 data
sheet available from Analog Devices, Inc., which should be
consulted in conjunction with this data sheet.
On-board components for the EVAL-AD7992 include two AD8691
operational amplifiers, two AD5245 digital potentiometers, one
AD780, which is, which is a pin programmable 2.5 V or 3 V ultra-
high precision band gap reference, and one TMP37 precision
temperature sensor.
Link options are provided in Table 1 and Table 2.
