DESCRIPTION
The VRE3050 is a low cost, high precision 5.0V
reference that operates from +10V. The device
features a buried zener for low noise and excellent
long term stability. Packaged in an 8 pin DIP and
SMT, the device is ideal for high resolution data
conversion systems.
The device provides ultrastable +5.000V output
with 鹵0.5000 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.
Significant improvements have been made in
other performance parameters as well, including
initial accuracy, warm-up drift, line regulation, and
long-term stability, making the VRE3050 series
the most accurate reference available.
For enhanced performance, the VRE3050 has an
external trim option for users who want less than
0.01% initial error.
For ultra low noise
applications, an external capacitor can be
attached between the noise reduction pin and the
ground pin.
The VRE3050 is recommended for use as a
reference for 14, 16, or 18 bit data converters
which require an external precision reference.
The device is also ideal for calibrating scale factor
on high resolution data converters. The VRE3050
offers superior performance over monolithic
references.
