FEATURES

•• VERY HIGH ACCURACY: 5.000 V ±0.4 mV

•• EXTREMELY LOW DRIFT: 0.6 ppm/°C -55°C to +125°C

•• EXCELLENT STABILITY: 6 ppm/1000 Hrs. Typ.

•• EXCELLENT LINE REGULATION: 6 ppm/V Typ.

•• WIDE SUPPLY RANGE: ±13.5 V to ±22.0 V

•• HERMETIC 14-PIN CERAMIC DIP

•• MILITARY PROCESSING OPTION

DESCRIPTION

provide ultrastable +5.000 V (VRE105) and
±5.000 V (VRE107) outputs with ±0.4 mV initial
accuracy and temperature coefficient as low as

0.6 ppm/°C over the full military temperature
range. This impovement in accuracy is made
possible by a unique, proprietary 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
VRE105 series the most accurate and stable 5V
references available.

VRE105 series devices are available in two operating temperature ranges, -25°C to +85°C and -55°C to
+125°C, and two performance grades. All devices are packaged in 14-pin hermetic ceramic packages for
maximum long-term stablity. "M" versions are screened for high reliability and quality.

Superior stability, accuracy, and quality make these references ideal for precision applications such as A/D
and D/A converters, high accuracy test and measurement instrumentation, and tranducer excitation.
