LM4040CIM3-3.0+T Integrated Circuits (ICs)

The LM4040CIM3-3.0+T is a precision voltage reference device that is part of the family of precision Voltage Reference devices contained in the Power Management IC (PMIC) group. It features an exceptionally low temperature coefficient and an extremely high accuracy over temperature, which is achieved by combining an extremely accurate band-gap reference with a CMOS operational amplifier.

The LM4040CIM3-3.0+T PMIC voltage reference works in four key components. First is the voltage-to-current converter (V/I) which takes an input voltage and converts it to a current. Second is the output buffer, which takes the current output from the V/I and amplifies it to the required output voltage. Third is the bandgap reference circuit which provides stable and accurate reference voltages over a wide temperature range. Finally, the fourth component is the temperature compensation circuit which regulates the output voltage to maintain accuracy regardless of changing temperature conditions.

The LM4040CIM3-3.0+T is a temperature compensated voltage reference device that provides a high-performance substitute for low-cost, non-temperature compensated references. With its low temperature coefficient, near-perfect accuracy over temperature, and up to 3V output voltage that can drive up to 100mA of load current, the LM4040CIM3-3.0+T is an ideal choice for any design requiring tight regulation over temperature and low cost. In addition, the low-noise operational amplifiers provide a stable output voltage in the presence of AC noise and power supply transients.

The LM4040CIM3-3.0+T also has a wide range of applications, ranging from powering LED displays and lighting fixtures, to precision voltage labels, to general reference and signal conditioning circuits. The device’s high-precision accuracy, low-temperature operating range, and ability to drive up to 100mA make it ideal for use in a variety of precision voltage-controlled applications.

The LM4040CIM3-3.0+T is extremely well suited for applications that require low voltage references, such as portable electronics, laptops, cell phones, RAM and flash memories, wireless communication systems, automotive applications, as well as network terminating equipment. It is available in the space-saving 3-pin SOT-23 and SOIC-8 packages for easy PCB mounting, and with its low power consumption, the device offers very low power dissipation and extended battery life for mobile applications.

In conclusion, the LM4040CIM3-3.0+T is a high-performance, low-cost and space-saving voltage reference device that provides accurate voltage reference over a wide temperature range. The high-precision accuracy, low-temperature operation, and low power consumption combined with its ability to drive up to 100mA make it the ideal choice for a wide range of precision, low-voltage-controlled applications.
