The Texas Instruments (TI) LM404x series of shunt voltage references are versatile, easy-to-use references for a vast array of applications, including data-acquisition systems, power supplies and power-supply monitors, instrumentation and test equip- ment, and battery-powered portable electronics. These shunt voltage references require no external capacitors for operation and are stable with all capacitive loads. Additionally, the reference offers low dynamic impedance, low noise and a low temperature coefficient to ensure a stable output voltage over a wide range of operating current and temperatures.
