General Description

The ECV321 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 1.8V to 5.5V. Typical low quiescent supply

current of 55µA in one 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 ECV321 is available in SOT23-5L and SOP-8L

packages. The extended temperature range of -40

to

+125

over all supply voltages offers additional design

flexibility.
