General Description

The EC5742 series amplifiers are single supply, low power CMOS dual operational amplifier, these amplifiers offer bandwidth of 9KHz, rail-to-rail inputs and outputs, and single-supply operation from 1.4V to 5.5V.

Low quiescent supply current of 1μA and very low input bias current of 1pA 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 EC5742 is available in SOP-8 and MSOP-8 packages.

The extended temperature range of -40∘C to +85∘Cover all supply voltages offers additional design flexibility.
