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 applications 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.
