The LM4060 is a family of high-precision shunt voltage references. The LM4060 family offers low 20ppm/°C temperature coefficient and 0.05% high precision initial accuracy. The LM4060 design eliminates the need for an external stabilizing capacitor and provides stability with capacitive loads up to 4.7µF. The LM4060 is offered in several fixed reverse breakdown voltages: 1.25V, 1.5V, 1.6V, 1.65V, 2.048V, 2.5V, 3V, 3.3V, 4.096V, 5V. The flexible voltage options make the LM4060 a companion device for ADCs, DACs, and level shifting signal conditioning circuits.

The LM4060 supports a maximum operating current up to 50mA to support a wide range of loads. The wide load current support allows for powering of ADCs, DACs, and MCUs while providing a stable voltage reference. The LM4060 functionality is similar to a Zener diode where the cathode voltage is constant above the minimum operating current. The LM4060 can be powered from a wide input supply voltage but an external resistor is required.

The LM4060 is specified for −40°C and 125°C, which enables operation across various industrial applications.
