5V, 12-Bit Serial 4µS ADC
This Application Note describes the evaluation board for the AD7895 12-Bit A/D converter. The AD7895 is a fast, 4µS successive approximation ADC which operates from a single +5V supply. It incorporates an on chip track/hold amplifier, an on-chip clock and a high speed serial interface. Full data on the AD7895 is available in the AD7895 data sheet available from Analog Devices and should be consulted in conjunction with this Application 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 AD713 quad op-amp used to buffer and bias (if required) the analog input. There are various link options which are explained in detail on page 2.
The evaluation board is compatible with the EVALUATION BOARD CONTROLLER
