General Description

The EC5721 is a single supply, low power CMOS operational amplifier; these amplifiers offer bandwidth of 1MHz, rail-to-rail inputs and outputs, and single-supply operation from 2.2V to 5.5V.
Typical low quiescent supply current of 40μA in single operational amplifier within one chip and very low input bias current of 10pA make the devices an ideal choice for low offset, low power consumption and high impedance pplications such as smoke detectors, photodiode amplifiers, and other sensors.
The EC5721 is available in SOT23-5 and SOP-8 packages.
The extended temperature range of -40 ℃ to +125 ℃over all supply voltages offers additional design flexibility.
