board crystal, or an off-board clock source.

l DIP switch selectable or micro port

controllable:

- Unipolar/Bipolar input range

- Sleep Mode-All Cal Modes

l On-board Decimation Counter

- Micro Port (CS5501 & CS5503)

Description

The CDB5501/CDB5503 is an evaluation board de-

signed for maximum flexibility when evaluating the

CS5501/CS5503 A/D converters. The board can easily

be configured to evaluate all the features of the

CS5501/CS5503, including changes in master clock

rate, calibration modes, output decimation rates, and in-

terface modes.

The evaluation board interfaces with most microcontrol-

lers and allows full control of the features of the CS5501

or CS5503. DIP switch selectable control is also avail-

able in the event a microcontroller is not used. The

evaluation board also offers computer data interfaces in-

cluding RS-232 and parallel port outputs for evaluating

the CS5501.

All calibration modes are selectable including Self-Cal,

System Offset Cal, and System Offset and System Gain

Cal. A calibration can be initiated at any time by pressing

the CAL pushbutton switch.
