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 voltage-

noise 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-to-

rail and their input common mode voltage range includes

ground. The maximum input offset of these amplifiers is less

than 5mV.

The EC5821are unity gain stable witha gain-bandwidth

flexibility.
