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.
