3 Description
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.
