CDB5012 CDB5012A
CDB5014 CDB5016
Evaluation Board for CS5012, CS5012A, CS5014,
CS5016 ADC’s
Features
General Description
The CDB5012/4/6 is an evaluation board that eases the
laboratory characterization of any of the CS5012,
CS5012A, CS5014 and CS5016 A/D converters. The
board can be easily reconfigured to simulate any com-
bination of sampling, master clock, calibration, and input
range conditions.
The converter’s parallel output data are available at a
40 pin strip header allowing easy interfacing to PC’s or
microprocessor busses. Output data is also available in
serial form at SCLK and SDATA coaxial BNC connec-
tors.
Evaluation can also be performed over a wide range of
input spans using the on-board reference circuitry. Fur-
thermore, the CDB5012, CDB5012A, CDB5014,
CDB5016 features DIP-switch selectable unipolar/bipo-
lar input ranges and the interleave calibration mode.
Calibration can be initiated at any time by momentarily
depressing a reset pushbutton.
