MCP1501T-12E/SN

MCP1501T-12E/SN is a precision user-adjustable operational amplifier and reference voltage source. It is a low-power monolithic integrated circuit (IC) designed for use as a high accuracy pre-engergized amplifier or a universal reference. The MCP1501T-12E/SN comes in a tiny 8-lead SOT-23surface-mount package. It features low power consumption, high noise immunity and a low-noise sinc filter for improved signal integrity.

Applications

The MCP1501T-12E/SN is designed for low-cost, low-power applications such as microprocessor/microcontroller voltage regulation and battery management equipment. It can also be used as an adjustable voltage reference for precision audio, communication, and instrumentation circuits. Its small size also makes it ideal for applications requiring small form factor solutions.

Working Principle

The MCP1501T-12E/SN is a low-power and low-noise two-terminal device. It can be configured as either a voltage reference or an operational amplifier depending on how it is connected. Internally, there is an internal bandgap design that creates a stable reference voiltage. This reference voltage is that compared to the voltage at the two external pins. If the two pins are at the same voltage, then the output is at the reference voltage. If the two pins are not at the same voltage, then the output follows the input voltage. The differential amplifier used to sense the voltage difference has a very low Noise figure (1.9 nV/√Hz), which is ideal for low noise circuits.

In addition to the low-noise and low-power features, the MCP1501T-12E/SN is also capable of providing very high accuracy (0.1%) thanks to its high-precision internal bandgap design. This design also allows for continuous adjustment of the reference voltage, so that it can be easily adjusted to the desired output voltage.

Conclusion

The MCP1501T-12E/SN is an ideal solution for low-cost, low-power, and high-accuracy voltage references. It offers an internal low-noise sinc filter, high accuracy operation and adjustable reference voltage. It is also available in a small surface-mount package. These features make it ideal for use in microprocessor/microcontroller voltage regulation and battery management equipment, as well as precision audio, communication and instrumentation circuits.
