DESCRIPTION
The VRE404 is a low cost, high precision, ±4.5V
reference.
packages, the device is ideal for new designs that
need a high performance reference.
The device provides ultrastable ±4.500V output
with ±0.450 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.
