DESCRIPTION
The VRE402 is a low cost, high precision, 鹵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 device provides ultrastable 鹵2.500V output
with 鹵0.250 mV (.01%) initial accuracy and a
temperature coefficient of 0.6 ppm/擄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.
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.
