LM4030

SOT-23 Ultra-High Precision Shunt Voltage Reference

General Description

Features

The LM4030 is an ultra-high precision shunt voltage refer-

ence, having exceptionally high initial accuracy (0.05%) and

temperature stability (10ppm/°C). The LM4030 is available

with fixed voltage options of 2.5V and 4.096V. Despite the tiny

SOT23 package, the LM4030 exhibits excellent thermal hys-

teresis (75ppm) and long-term stability (40ppm) as well as

immunity to board stress effects.

High output voltage accuracy 0.05%

■

Low temperature coefficient 10 ppm/°C

Extended temperature operation -40-125°C

Excellent thermal hysteresis, 75ppm

Excellent long-term stability, 40ppm

High immunity to board stress effects

The LM4030 is designed to operate without an external ca-

pacitor, but any capacitor up to 10µF may be used. The

LM4030 can be powered off as little as 120µA (max) but is

capable of shunting up to 30mA continuously. As with any

shunt reference, the LM4030 can be powered off of virtually

any supply and is a simple way to generate a highly accurate

system reference.

Capable of handling 50 mA transients

Voltage options 2.5V, 4.096V

Applications

Data Acquisition/Signal path

■

The LM4030 is available in three grades (A, B, and C). The

best grade devices (A) have an initial accuracy of 0.05% with

guaranteed temperature coefficient of 10 ppm/°C or less,

while the lowest grade parts (C) have an initial accuracy of

0.15% and a temperature coefficient of 30 ppm/°C.
