Applications
The VRE410 is recommended for use as a refer-
ence for high precision D/A and A/D converters
which require an external precision reference.
The device is also ideal for calibrating scale factor
on high resolution A/D converters. The VRE410
offers superior performance over monolithic refer-
ences.
DESCRIPTION
The VRE410 is a low cost, high precision, ±10 V refer-
ence. Available in a 14-pin SMT package, the device
is ideal for new designs that need a high performance
reference.
The device provides ultrastable ±10 V output with ±1.0
mV (.01%) initial accuracy and a temperature coeffi-
cient of 0.6 ppm/°C. This improvement in accuracy is
made possible by a unique, patented multipoint laser
compensation technique.
Another key feature of this reference is the 0.5 mV
maximum tracking error between the positive and neg-
ative output voltages over the full operating tempera-
ture range. This is extremely important in high perfor-
mance systems for reducing overall system errors.
