Product Summary

The l4051aq is a shunt voltage reference. It is versatile easy-to-use references suitable for a wide array of applications. The l4051aq is available in a fixed 1.225-V output or an adjustable output whose voltage is determined by an external resistor divider. The device requires no external capacitors for operation and is stable with all capacitive loads. Additionally, the reference offers low dynamic impedance, low noise, and low temperature coefficient to ensure a stable output voltage over a wide range of operating currents and temperatures. The applications of the l4051aq include Data-Acquisition Systems, Power Supplies and Power-Supply Monitors, Instrumentation and Test Equipment, Process Control, Precision Audio, Automotive Electronics, Energy Management/Metering and Battery-Powered Equipment.
