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 ref-

erence for 14, 16, or 18 bit data converters which

require an external precision reference. The de-

vice is also ideal for calibrating scale factor on

high resolution data converters. The VRE3050

offers superior performance over monolithic ref-

erences.

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 external

capacitor can be attached between the noise reduction

pin and the ground pin.
