Texas Instruments LM4060/-Q1 High Precision Shunt Voltage References
Texas Instruments LM4060/-Q1 High Precision Shunt Voltage References offer a low 20ppm/°C temperature coefficient and 0.05% high-precision initial accuracy. The LM4060 and LM4060-Q1 references design eliminate the need for an external stabilizing capacitor and provides stability with capacitive loads up to 4.7µF. The LM4060 and LM4060-Q1 are 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-Q1 devices are AEC-Q100 qualified for automotive applications.
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.
