Description
Edge6435/6436
Per-Pin Electronics
Companion DAC
The Edge6435/6436 is a low-cost, 40-channel, monolithic The Edge6435/6436 features 2 ranks of input latches

at one time.
The Edge6435/6436 features independent buffered
voltage and current outputs that are serially programmed
and can be used to provide all of the reference levels
required for up to 8 channels of pin electronics in an ATE
system.
Designated Voltage Output DACs
– Wide Voltage Range (16.75V)
– Adjustable Full-Scale Range
– Adjustable Minimum Offset Voltage
– 13-bit Resolution
– 11-bit Accuracy (E6436)
– 10-bit Accuracy (E6435)
Selectable Voltage/Current Output DACs

For Automated Test Equipment, the Edge6435/6436 can
support Pin Electronics and Parametric Measurement Units
whose outputs are in the range of –3.25V to +13V, and
Driver Super Voltages to +13V after calibration. It provides
10 or 5 per pin levels for 4 or 8 channels respectively.
The Edge6435/6436 is designed such that DACs may be
shared for various levels whereby minimizing the total
number of DACs required in a specific application.

On-chip, digital storage of offset and gain calibration
coefficients allow the E6435/6436 output levels to be
programmed using “Ideal Code”, helping to reduce some
of the complexity and time normally associated with
programming level DACs in ATE systems.
Applications
PINCAST allows the Edge6435/6436 to further reduce
this complexity and time by allowing channels across
multiple Edge6435/6436 devices to be digitally assigned
to up to 8 distinct sets that can be addressed and
programmed with a limited number of instructions.
• Automated Test Equipment (ATE)
• Cost Sensitive applications requiring multiple
programmable voltage and currents
