DESCRIPTION

The DEM-ADS7843E/45E evaluation fixture is de-

signed for quick evaluation of Burr-Brown’s

ADS7843E (4-wire) and ADS7845E (5-wire) touch-

panel controllers. The board has features that allow the

user to evaluate all the functions of the analog-to-

digital converter. The options offered to the user

include a flexible clock generator circuit, an analog

breadboard area, a digital breadboard area, and an

easily-configurable voltage reference. The DEM-

ADS7843E/45E has been designed to accommodate

stand-alone operation, allowing the user to easily con-

nect directly to 4-wire (ADS7843E) or 5-wire

(ADS7845E) touch-screen panels and to an external

processor. This evaluation fixture has a quick-release

socket for easy evaluation of mulitiple converters or a

solder footprint to allow the user to solder the DUT

directly to the board.
