AD7723: 16-Bit, 1.2 MSPS CMOS, Sigma-Delta ADC
Introduction
This Technical Note describes the evaluation board for the AD7723 16-Bit, 1.2MSPS, CMOS, Sigma-Delta ADC. The AD7723 evaluation board is designed to demonstrate the AD7723's performance and to provide a flexible interface for a variety of applications. Full data on the AD7723 is available in the AD7723 data sheet available from Analog Devices and should be consulted in conjunction with this Technical Note when using the Evaluation Board.
The AD7723 can operate with its internal reference, or the on-board AD780 precision bandgap reference can be used as an external reference. The analog input is conditioned using 2 AD8047 op-amps, and this circuit can be configured to drive the AD7723 with complimentary signals.
The evaluation board is compatible with the EVALUATION BOARD CONTROLLER.
