VRE3050

Precision Voltage Reference

FEATURES

DESCRIPTION

The VRE3050 is a low cost, high precision 5 V refer-

ence that operates from +10 V. The device features

a buried zener for low noise and excellent long term

stability. Packaged in an 8-pin SMT, the device is ideal

for high resolution data conversion systems.

♦ +5 V Output, ± 0.5 mV (.01%)

♦ Temperature Drift: 0.6 ppm/ºC

♦ Low Noise: 3 μV_P-P(0.1Hz-10Hz)

♦ Low Thermal Hysterisis: 1 ppm Typical

♦ ±15mA Output Source and Sink Current

♦ Excellent Line Regulation: 5 ppm/V Typical

♦ Optional Noise Reduction and Voltage Trim

♦ Industry Standard Pinout: 8-pin Surface Mount

Package

The device provides ultrastable +5 V output with ±0.5

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. Signiﬁcant improvements

have been made in other performance parameters as

well, including initial accuracy, warm-up drift, line reg-

ulation, and long-term stability, making the VRE3050

series the most accurate reference available.

APPLICATIONS

The VRE3050 is recommended for use as a refer-

ence for 14, 16, or 18 bit data converters which re-

quire 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.

For enhanced performance, the VRE3050 has an ex-

ternal trim option for users who want less than 0.01%

initial error. For ultra low noise applications, an exter-

nal capacitor can be attached between the noise re-

duction pin and the ground pin.
