LM4041Q
AUTOMOTIVE GRADE 1.225V AND ADJUSTABLE PRECISION REFERENCE
Description
The LM4041 is a bandgap circuit designed to achieve a precision
micro-power voltage reference of 1.225 V; it is also available in an
adjustable version. The device is available in the small outline SOT23
surface mount package which is ideal for applications where space
saving is important.
The fixed output version is available in 0.5% C grade and 1% D grade
while the adjustable is only available in D grade. 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 for
automotive applications.
The LM4041Q has been qualified to AEC-Q100 Grade 1 and is
Automotive Grade supporting PPAPs.
