Voltage Reference
4 Voltage Reference chips — pinouts, specs, and datasheets.
LM4030 · Texas Instruments
The LM4030 is an ultra-high precision shunt voltage reference with fixed output voltages of 2.5V and 4.096V, offering high initial accuracy and temperature stability.
LM4040 · Texas Instruments
The LM4040 is a precision micropower shunt voltage reference available in fixed outputs from 2.048 V to 10 V. It needs no external capacitor, is stable with any capacitive load, and operates from 45 uA to 15 mA.
REF2030 · Texas Instruments
The REF2030 is a dual reference voltage IC providing VREF and VREF/2 outputs for single-supply systems with low drift, high accuracy, and low power consumption.
TL431 · Texas Instruments
The TL431 is an adjustable precision shunt voltage reference with a 2.5V reference. An external resistor divider programs its output from 2.5V up to 36V, commonly used for regulation and feedback.
