Datasheet Maxim MAX4043

19-1377; Rev 1; 9/05 Single/Dual/Quad, Low-Cost, SOT23,
Micropower Rail-to-Rail I/O Op Amps
____________________________Features 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 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. ♦ Single-Supply Operation Down to +2.4V 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 powersupply voltage to be used for signal range. The combination of low input offset voltage, low input bias current,
and high open-loop gain makes them suitable for lowpower/low-voltage precision applications.
The MAX4040 is offered in a space-saving 5-pin SOT23
package. All specifications are guaranteed over the
-40°C to +85°C extended temperature range. ________________________Applications
