Description
The Hewlett-Packard Low Current Bar Code Digitizer IC allows designers to incorporate the high ambient light rejection and low power consumption features of the HBCS-AXXX/TXXX wands into their own bar code circuitry. The HBCC-0500 is packaged in a 24 pin SOIC plastic package.
output of different sensor “bins” is equalized by varying the amplitude of the LED drive current.
The sensor output has two components; DC due to ambient light, and AC from the bar code label.
