DESCRIPTION

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

reference.

packages, the device is ideal for new designs that

need a high performance reference.

The device provides ultrastable ±2.500V output

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

temperature coefficient of 0.6 ppm/°C.

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.
