The OP221 is a monolithic dual operational amplifier that can e used either in single or dual supply operation. The wide upply voltage range, wide input voltage range, and low supply urrent drain of the OP221 make it well-suited for operation rom batteries or unregulated power supplies.
The excellent specifications of the individual amplifiers com-ined ith the tight matching and temperature tracking between channels 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 comp-ensated and protected.
Matching between channels is provided on all critical parameters including input offset voltage, tracking of offset voltage vs. temperature, non-inverting bias currents, and common-mode rejection.
