Single/Dual/Quad, +1.8V/10µA, SOT23,

Beyond-the-Rails Op Amps

General Description

Features

The MAX4240–MAX4244 family of micropower op amps

operate from a single +1.8V to +5.5V supply or dual

0.ꢀV to 2.ꢁ5V supplies and haꢂe ꢃeyondꢄtheꢄꢅailsꢆ

inputs and railꢄtoꢄrail output capabilities. These ampliꢄ

fiers proꢂide a ꢀ0kHz gainꢄbandwidth product while

using only 10µA of supply current per amplifier. The

MAX4241/MAX4243 haꢂe a lowꢄpower shutdown mode

that reduces supply current to less than 1µA and forces

the output into a highꢄimpedance state. Although the

minimum operating ꢂoltage is specified at +1.8V, these

deꢂices typically operate down to +1.5V. The combinaꢄ

tion of ultraꢄlowꢄꢂoltage operation, beyondꢄtheꢄrails

inputs, railꢄtoꢄrail outputs, and ultraꢄlow power conꢄ

sumption makes these deꢂices ideal for any portable/

twoꢄcell batteryꢄpowered system.

♦ Ultra-Low-Voltage Operation:

Guaranteed Down to +1.8V

Typical Operation to +1.5V

♦ Ultra-Low Power Consumption:

10µA Supply Current per Amplifier

1µA Shutdown Mode (MAX4241/MAX4243)

Up to 200,000 Hours Operation from Two AA

Alkaline Cells

♦ Beyond-the-Rails Input Common-Mode Range

♦ Outputs Swing Rail-to-Rail

♦ No Phase Reversal for Overdriven Inputs

♦ 200µV Input Offset Voltage

These amplifiers haꢂe an input commonꢄmode range

that extends 200mV beyond each rail, and their outꢄ

puts typically swing to within ꢀmV of the rails with a

100kΩ load. ꢃeyondꢄtheꢄrails input and railꢄtoꢄrail outꢄ

put characteristics allow the full powerꢄsupply ꢂoltage

to be used for signal range. The combination of low

input offset ꢂoltage, low input bias current, and high

openꢄloop gain makes them suitable for lowꢄpower/lowꢄ

ꢂoltage precision applications.

♦ Unity-Gain Stable for Capacitive Loads up to 200pF

♦ 90kHz Gain-Bandwidth Product

♦ Available in Space-Saving 5-Pin SOT23 and

8-Pin µMAX^®Packages
