LM4030 SOT-23 Ultra-High Precision Shunt Voltage Reference

Check for Samples: LM4030

FEATURES

DESCRIPTION

The LM4030 is an ultra-high precision shunt voltage

reference, 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 SOT-23 package, the

LM4030 exhibits excellent thermal hysteresis

(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

Capable of Handling 50 mA Transients

Voltage Options 2.5V, 4.096V

The LM4030 is designed to operate without an

external capacitor, 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.

Communications

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

C). The best grade devices (A) have an initial

accuracy of 0.05% with ensured 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.
