Single/Dual/Quad, Low-Cost, SOT23, Micropower Rail-to-Rail I/O Op Amps MAX4040–MAX4044 ________________General Description ____________________________Features
The MAX4040–MAX4044 family of micropower op amps ♦
Single-Supply Operation Down to +2.4V
operates from a single +2.4V to +5.5V supply or dual ±1.2V to ±2.75V supplies and have rail-to-rail input and ♦
Ultra-Low Power Consumption:
output capabilities. These amplifiers provide a 90kHz
10µA Supply Current per Amplifier
gain-bandwidth product while using only 10µA of supply
1µA Shutdown Mode (MAX4041/MAX4043)
current per amplifier. The MAX4041/MAX4043 have a ♦
Rail-to-Rail Input Common-Mode Range
low-power shutdown mode that reduces supply current to less than 1µA and forces the output into a high-imped- ♦
Outputs Swing Rail-to-Rail
ance state. The combination of low-voltage operation, ♦
No Phase Reversal for Overdriven Inputs
rail-to-rail inputs and outputs, and ultra-low power con- sumption makes these devices ideal for any ♦
200µV Input Offset Voltage
portable/battery-powered system. ♦
Unity-Gain Stable for Capacitive Loads up to 200pF
These amplifiers have outputs that typically swing to within 10mV of the rails with a 100kΩ load. Rail-to-rail ♦
90kHz Gain-Bandwidth Product
input and output characteristics allow the full power- ♦
Available in Space-Saving 5-Pin SOT23 and
supply voltage to be used for signal range. The combi-
8-Pin µMAX® Packages
nation of low input offset voltage, low input bias current, and high open-loop gain makes them suitable for low- power/low-voltage precision applications.
