LM4040D - Precision micropower shunt voltage reference

Download the LM4040D datasheet PDF. This datasheet also covers the LM4040 variant, as both devices belong to the same precision micropower shunt voltage reference family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM4040 is a low power and high accuracy shunt voltage reference providing a stable output voltage over the industrial temperature range (-40 to +125 °C), with a maximum temperature coefficient of 70 ppm/°C.

It is available in 0.1%, 0.2%, 0.5% and 1% initial accuracy versions.

Key Features

  • Fixed 2.048 V, 2.5 V, 3.0 V, 4.096 V and 5.0 V output voltages.
  • Ultra low operating current: 10 µA at 25 °C.
  • High precision @ 25 °C: +/- 0.1% (LM4040A), +/- 0.2% (LM4040B), +/- 0.5 % (LM4040C), +/- 1% (LM4040D).
  • Very low LF noise: typ.10 µ Vp-p.
  • Stable when used with capacitive loads.
  • Industrial (-40 to +125 °C) temperature range.
  • 70 ppm/°C max. temperature coefficient.
  • Available in SOT23-3L and SOT323-5L packages Applicati.
