MAX4038 - Low IBIAS / +1.4V/800nA / Rail-to-Rail Op Amps with +1.2V Buffered Reference

Download the MAX4038 datasheet PDF. This datasheet also covers the MAX variant, as both devices belong to the same low ibias / +1.4v/800na / rail-to-rail op amps with +1.2v buffered reference family and are provided as variant models within a single manufacturer datasheet.

General Description

The single MAX4036/MAX4037 and dual MAX4038/ MAX4039 operational amplifiers operate from a single +1.4V to +3.6V (without reference) or +1.8V to +3.6V (with reference) supply and consume only 800nA of supply current per amplifier, and 1.1µA for the optional reference.

Key Features

  • Ultra-Low 800nA per Amplifier Supply Current.
  • Ultra-Low 1.4V Supply Voltage Operation (1.8V for MAX4037/MAX4039).
  • Rail-to-Rail Outputs Drive 5kΩ and 5000pF Load.
  • 1.232V ±0.5%, 120ppm/°C (max) Reference (MAX4037/MAX4039).
  • No External Reference Bypass Capacitor Required.
  • No Phase Reversal for Overdriven Inputs.
  • Low 1.0pA (typ) Input Bias Current.
  • Low 200µV Input Offset Voltage.
  • Unity-Gain Stable.
  • Available i.

19-3142; Rev 2; 11/04 Low IBIAS, +1.4V/800nA, Rail-to-Rail Op Amps with +1.2V Buffered Reference General Description The single MAX4036/MAX4037 and dual MAX4038/ MAX4039 operational amplifiers operate from a single +1.4V to +3.6V (without reference) or +1.8V to +3.6V (with reference) supply and consume only 800nA of supply current per amplifier, and 1.1µA for the optional reference. The MAX4036/MAX4038 feature a common-mode input voltage range from 0V to VDD - 0.4V at VDD = 1.4V. The MAX4037/MAX4039 feature a 1.232V voltage reference capable of sourcing 100µA and sinking 20µA. The MAX4036–MAX4039s’ rail-to-rail outputs drive 5kΩ loads to within 25mV of the rails.
