Evaluation Kits (1)
Evaluation board for the AD7898 which is a fast 12-bit ADC that operates from a single +5 V supply and is housed in an 8-pin SOIC. Full data on the AD7898 is available in the AD7898 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.
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 CS/CONVST input, VDRIVE input, SDATA input, SCLK input, REFIN input and the VIN input.
