Product Overview

The LM4040 series precision micropower shunt Voltage Reference for use with energy management. The LM4040 series of shunt voltage reference is 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 LM4040 uses fuse and zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances, ranging from 0.1% (maximum) for the A grade to 1% (maximum) for the D grade. The LM4040xI is characterized for operation over an ambient temperature range of -40 to 85°C. The LM4040xQ is characterized for operation over an ambient temperature range of -40 to 125°C.
  • Stable with all capacitive loads
  • No output capacitor required
  • 35μVRMS Typical low output noise
  • 45μA to 15mA Typical wide operating current range
