PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES
Description
The LM4041 is a bandgap circuit designed to achieve a
precision micro-power voltage reference of 1.225 V. The
device is available in the small outline SOT23 and SC70-5
surface mount packages which are ideal for applications
where space saving is important.
Both packages are available to 0.5% C grade and 1%
D grade for precision applications. Excellent performance is
maintained over the 60µA to 12mA operating current range
with a typical temperature coefficient of only 20ppm/°C. The
device has been designed to be highly tolerant of capacitive
loads so maintaining excellent stability.
This device offers a pin for pin compatible alternative to the
LM4041 voltage reference in both adjustable and 1.225V
output variants.
