Product Summary

The LM4040A25IDBZR is a shunt voltage reference. It is a versatile, easy-to-use reference that caters to a vast array of applications. The 2-pin fixed-output 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 LM4040A25IDBZR uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances, ranging from 0.1% (max) for the A grade to 1% (max) for the D grade. Thus, a great deal of flexibility is offered to designers in choosing the best cost-to-performance ratio for their applications. Applications include Data-Acquisition Systems, Power Supplies and Power-Supply, onitors, Instrumentation and Test Equipment, Process Controls, Precision Audio, Automotive Electronics, Energy Management and Battery-Powered Equipment.
