TEST AND MEASUREMENT PRODUCTS

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 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

Selectable Voltage/Current Output DACs

Designated Current Output DACs

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.

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.

The Edge6435/6436 features 2 ranks of input latches

into each DAC, whereby all DAC values may be updated

at one time.

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.
