Single/Dual/Quad, Low-Cost, SOT23,
Micropower Rail-to-Rail I/O Op Amps
________________General Description
____________________________Features
The MAX4040–MAX4044 family of micropower op amps
operates from a single +2.4V to +5.5V supply or dual
±±.2V to ±2.ꢀ5V supplies and haꢁe railꢂtoꢂrail input and
output capabilities. These amplifiers proꢁide a 90kHz
gainꢂbandwidth product while using only ±0µA of supply
current per amplifier. The MAX404±/MAX4043 haꢁe a
lowꢂpower shutdown mode that reduces supply current
to less than ±µA and forces the output into a highꢂimpedꢂ
ance state. The combination of lowꢂꢁoltage operation,
railꢂtoꢂrail inputs and outputs, and ultraꢂlow power conꢂ
sumption makes these deꢁices ideal for any
portable/batteryꢂpowered system.
♦ Single-Supply Operation Down to +2.4V
♦ Ultra-Low Power Consumption:
10µA Supply Current per Amplifier
1µA Shutdown Mode (MAX4041/MAX4043)
♦ 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 haꢁe outputs that typically swing to
within ±0mV of the rails with a ±00kΩ load. Railꢂtoꢂrail
input and output characteristics allow the full powerꢂ
supply ꢁoltage to be used for signal range. The combiꢂ
nation of low input offset ꢁoltage, low input bias current,
and high openꢂloop gain makes them suitable for lowꢂ
power/lowꢂꢁoltage precision applications.
