1MHz, 1.8V, CMOS,
Rail-to-Rail Operational Amplifier
ECV321
General Description
Features
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.
