MAX4039 Datasheet

Low Ibias / +1.4v/800na / Rail-to-rail Op Amps With +1.2v Buffered Reference

Manufacturer: Maxim Integrated (now Analog Devices)

This datasheet includes multiple variants, all published together in a single manufacturer document.

MAX4039 Overview

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.

MAX4039 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 in Tiny UCSP, SC70, SOT23, TDFN, and µMAX Packages
