General Description

The EC5821 is wideband, low-noise, low-distortion dual operational amplifier, that offer rail-torail inputs / outputs and single supply operation down to 2.2V.

They draw 1.6mA of quiescent supply current while featuring ultra-low distortion(0.0002% THD+N), as well as low input voltagenoise density (15nV/Hz) and low input currentnoise density (0.5fA/Hz).These features make the devices an ideal choicef or applications that require low distortion and/or low noise.

These amplifiers have inputs and outputs which swing rail-torail and their input common mode voltage range ncludes
ground.

The maximum input offset of these amplifiers is less than 5mV.

The EC5821are unity gain stable witha gain-bandwidth of 10MHz.

The EC5821 is available in SOT23-5 and SOP 8 packages.

The extended temperature range of -40°C to +125°C over all supply voltages offers additional design flexibility.
