350kHz, Zero-Drift, CMOS,
Rail-to-Rail Operational Amplifier
EC5731
General Description
Features
The EC5731 amplifier is single supply, micro-power, zero-
drift CMOS operational amplifier, the amplifier offer
bandwidth of 350kHz, rail-to-rail inputs and outputs, and
single-supply operation from 2.2V to 5.5V. EC5731 uses
chopper stabilized technique to provide very low offset
voltage (less than 20µV maximum) and near zero drift over
temperature. Low quiescent supply current of 20μA and
very low input bias current of 10pA make the devices an
ideal choice for low offset, low power consumption and high
impedance applications. The single EC5731 is available in
space-saving, SOT23-5 and SOP-8 package.The extended
temperature range of -40 ℃ to +125 ℃ over all supply
voltages offers additional design flexibility.
