3 Description
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.
