The LM4040BIZ-2.0/NOPB is a precision CMOS Micropower Voltage Reference. This device provides both the convenience of a two pin configuration—ground and output— and the accuracy and low drift of more expensive, three terminal voltage references. It operates over a wide 4.5 V to 40 V range and requires a minimum of only 350 μA of supply current. It is an ideal voltage reference solutions for power supply sequencing, power supplies and various other applications.

An important feature of the LM4040BIZ-2.0/NOPB is its low active supply current, making it an ideal choice for battery-powered or low power applications where other references consume more power. The device also features a tight specification, ensuring stable and long-term accurate operation. It offers a wide variety of voltage references, ranging from 0.2 V to 10 V, in both unipolar and split variants.

The LM4040BIZ-2.0/NOPB operates with a two-pin configuration. Its ground pin is connected to the input of the IC, and the output of the device is fed back to the input pin. The device uses a voltage divider network, which determines the output voltage of the device. It is configured to produce an output voltage that is either equal to or higher than the input voltage, in order to maintain its low power consumption.

The device also includes an internal bandgap reference, which provides a stable voltage reference voltage. This reference voltage is then used to set the voltage divider so that the output voltage of the device is accurately adjusted, regardless of variations in the input voltage or temperature. Additionally, the device also contains a temperature compensation network that ensures that the output voltage remains stable over a wide temperature range.

The LM4040BIZ-2.0/NOPB is designed primarily for low power, portable applications, such as cellular phones and small electronics. Its wide operating voltage range and tight specification make it ideal for a variety of applications, including power supplies, sequencing, over voltage protection, and many others. It is an ideal solution for providing an accurate reference voltage in applications where power consumption needs to be kept to a minimum.
