This Application Note describes the evaluation board for the AD7892-2 12-Bit A/D converter The AD7892-2 is a high speed, low power, 500ksps successive approximation ADC which operates from a single +5V supply. It incorporates an on chip track/hold Amplifier an internal +2. 5V reference and on- chip versatile Interface structures that allow both ser

ial and parallel connection to a Microprocessor This flexible serial Interface allows the AD7892-2 to connect directly to Digital Signal Processors ADSP-2101 TMS320C25 etc. ) and Microcontrollers (8XC51, 68HC11, etc. ). Full data on the AD7892-2 is available in the AD7892 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. 5 V or +3V ultra high precision bandgap reference and an input Buffer Amplifier to Buffer the Analog input.
