Texas Instruments LM4060 High Precision Shunt Voltage Reference
Texas Instruments LM4060 High Precision Shunt Voltage Reference offers a 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 Texas Instruments LM4060 supports a maximum operating current of up to 50mA to accommodate a wide range of loads. The wide-load current support allows powering ADCs, DACs, and MCUs while providing a stable voltage reference. The LM4060 operates similarly to a Zener diode, with the cathode voltage 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.
