DESCRIPTION

The VRE402 is a low cost, high precision, ±2.5V

reference. Packaged in 14 pin DIP or SMT

packages, the device is ideal for new designs that

need a high performance reference.

The VRE402 is recommended for use as a

reference for high precision A/D and D/A

converters which require an external precision

reference. The device is ideal for calibrating

scale factor on high resolution A/D converters.

The VRE402 offers superior performance over

monolithic references.

The device provides ultrastable ±2.500V output

with ±0.250 mV (.01%) initial accuracy and a

temperature coefficient of 0.6 ppm/°C.

This

improvement in accuracy is made possible by a

unique, patented multipoint laser compensation

technique developed by Thaler Corporation.

Another key feature of this reference is the 0.3 mV

maximum tracking error between the positive and

negative output voltages over the operating

temperature range. This is extremely important in

high performance systems for reducing overall

system errors.

For designs which use the DIP package in a

socket, there is a reference ground pin to

eliminate reference ground errors.

For package option add D for DIP or S for Surface

Mount to end of model number.
