Edge6420
Per-Pin Electronics
Companion DAC
HIGH-PERFORMANCE PRODUCTS – ATE
Description
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.
Voltage DACs
• Wide voltage (17V range)
• Adjustable full scale range
• Adjustable minimum output
• 13 bits resolution
Current DACs
• ~3.6 mA full scale range
• Adjustable full scale range
• 6/13 bits resolution
The DACs are programmed using a serial interface.
The inclusion of 64 total DACs into 1 package offers an
extremely high density, flexible solution normally
implemented using multiple components.
