Features
Edge6420
Per-Pin Electronics
Companion DAC
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
64 Total DACs/Package Including:
• Wide Voltage Output Range (17V Range); Useful
for Supervoltage
• 44 Voltage DACs / Package
• 20 Current DACs / Package
• Adjustable Full Scale Range
• Adjustable Output Voltage Offset
• Small 13x13mm BGA Package
• All DACs are Guaranteed Monotonic
Applications
• Test Equipment
• Applications requiring multiple programmable
voltage and currents
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.
