Automotive, 20ppm/°C maximum drift high precision shunt voltage reference

The LM4060-Q1 is a family of high-precision shunt voltage references. The LM4060-Q1 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-Q1 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-Q1 a companion device for ADCs, DACs, and level shifting signal conditioning circuits.

The LM4060-Q1 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-Q1 functionality is similar to a Zener diode where the cathode voltage is constant above the minimum operating current. The LM4060-Q1 can be powered from a wide input supply voltage but an external resistor is required.

The LM4060-Q1 is specified for −40°C and 125°C, which enables operation across various industrial applications.
