General Description

Features

♦ Ultra-Low 800nA per Amplifier Supply Current

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 refer-

ence. The MAX4036/MAX4038 feature a common-mode

♦ 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)

input voltage range from 0V to V

- 0.4V at V

= 1.4V.

♦ No External Reference Bypass Capacitor

The MAX4037/MAX4039 feature a 1.232V voltage refer-

ence capable of sourcing 100µA and sinking 20µA.

Required

♦ No Phase Reversal for Overdriven Inputs

♦ Low 1.0pA (typ) Input Bias Current

♦ Low 200μV Input Offset Voltage

♦ Unity-Gain Stable

The MAX4036–MAX4039s’ rail-to-rail outputs drive 5kΩ

loads to within 25mV of the rails. Ultra-low supply current,

low operating voltage, and rail-to-rail outputs make the

MAX4036–MAX4039 ideal for use in single-cell lithium-ion

(Li+), or two-cell NiCd/NiMH/alkaline battery-powered

applications.

♦ Available in Tiny UCSP, SC70, SOT23, TDFN, and

μMAX Packages

The MAX4036 is available in an SC70 package, the

MAX4037 in a SOT23 package, and the MAX4038/

♦ Available in -40°C to +125°C Temperature Range

(MAX4036A/MAX4038A)

MAX4039 in UCSP™, µMAX , and TDFN packages.
