Edge6435/6436
Per-Pin Electronics
Companion DAC
TEST AND MEASUREMENT PRODUCTS
Description
The Edge6435/6436 is a low-cost, 40-channel, monolithic
ATE level DAC solution manufactured in a wide-voltage
bi-CMOS process.
The Edge6435/6436 features 2 ranks of input latches
into each DAC, whereby all DAC values may be updated
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.
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.

• Low-Cost, Highly Integrated Multi-DAC Solution
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
• Automated Test Equipment (ATE)
• Cost Sensitive applications requiring multiple
programmable voltage and currents
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.
