Description
64 Total DACs/Package Including:
The Edge6420 is a monolithic device which has 64
integrated DACs that are designed specifically for all per
channel wide-voltage and current levels needed for pin
electronics inside automatic test equipment. The chip
can also be used for other applications requiring multiple
integrated voltage or current DAC outputs.
