Voltage reference, or voltage reference source, is a piece of electronic equipment which produces a fixed reference voltage. This reference voltage can be used to control the output voltage of an electronic device, allowing the device to maintain a consistent level of performance with changes in input voltage, temperature, or time.The LM4040C10IDCKR is a series of voltage references produced by Texas Instruments. It provides an accurate, low-drift, precision voltage reference for use in a wide range of power management, automotive, and medical applications, as well as communications, clock, and data storage equipment.This device, which uses a temperature compensated bandgap reference, is ideal for use in converters, regulators, or reference circuits for bidirectional current or voltage sensing, both in AC and DC applications. It delivers a stable output voltage of 0.625, 1.25, 2.5, 4, or 5V, with a temperature drift of 2ppm/°C.The LM4040C10IDCKR is a three-terminal device, consisting of a voltage reference output, an adjustable output, and a ground. When the voltage reference output is connected to the adjustable output, a reference voltage is produced.The differential output stage of the LM4040C10IDCKR consists of two matched transistors, with their emitter terminals connected to each other in the center of the package. The positive terminal is connected to one of the emitters and the negative terminal to the other. The output voltage is the difference of the two emitter voltages.The LM4040C10IDCKR features a large dynamic operating range, from –40°C to +125°C, without a need for external components. It also has low noise, low temperature coefficient, and excellent load regulation, as well as a wide ESD protection rating of up to 8kV.In terms of power consumption, the LM4040C10IDCKR draws an operating current of less than 10mA. This makes it well-suited for a variety of low-power applications, as well as battery-powered devices.Thanks to its small size, it can also be used in space-constrained applications. It is available in through-hole and surface-mount packages for easy assembly onto printed circuit boards.The LM4040C10IDCKR is suitable for use in a wide range of power management, automotive, medical, communications, and data storage applications, as well as other applications that require a reliable and accurate reference voltage.
