AD7495CB

This Technical Note describes the evaluation board for the AD7475/AD7495 which is a fast 12-bit high speed, low power successive-approximation ADCs. The parts operate from a sinlge 2.7 V to 5.25 V power supply and feature throughput rates up to 1 MSPS. Full data on the AD7475/AD7495 is available in the AD7475/AD7495 data sheet available from Analog Devices and should be consulted in conjunction with this Technical Note when using the Evaluation Board.

On-board components include an AD780 which is a pin programmable +2.5V or +3V ultra high precision bandgap reference and an AD711 op-amp used to buffer the analog input. There are various link options which are explained in detail on page 2.

Interfacing to this board is through a 96-way connector. This 96-way connector is compatible with the EVALUATION-BOARD CONTROLLER which is also available from Analog Devices. External sockets are provided for the REFIN input and the VIN input.
