GENERAL DESCRIPTION

The OP221 is a monolithic dual operational amplifier that can

be used either in single or dual supply operation. The wide

supply voltage range, wide input voltage range, and low supply

current drain of the OP221 make it well-suited for operation

from batteries or unregulated power supplies.

provide high performance in instrumentation amplifier designs.

The individual amplifiers feature very low input offset voltage,

low offset voltage drift, low noise voltage, and low bias current.

They are fully compensated and protected.

Matching between channels is provided on all critical parameters

including input offset voltage, tracking of offset voltage vs. tem-

perature, non-inverting bias currents, and common-mode rejection.

The excellent specifications of the individual amplifiers combined

with the tight matching and temperature tracking between channels
