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