3D Model
The LM4040 is a family of bandgap circuits designed to achieve precision micro-power voltage references of 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. The devices are available in 0.2% B-grade, 0.5% C-grade, and 1% D-grade initial tolerances. They are available in small outline SOT23 surface mount packages, which are ideal for applications where space is at a premium. Excellent performance is maintained over the 60µA to 15mA operating current range with a typical temperature coefficient of only 20ppm/°C. The device is designed to be highly tolerant of capacitive loads, which maintains excellent stability. This device offers a pin for pin compatible alternative to the LM4040 voltage reference.
This article provides you with a basic overview of the LM4040, including its pin descriptions, functions and specifications, etc., to help you quickly understand what LM4040 is.
