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.
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.
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.
