OP220: Dual Micropower Operational Amplifier
The OP-220 is a monolithic dual operational amplifier that can be used either in single or dual supply operation. The low offset voltage, and input offset voltage tracking as low as 1.0µV/°C, make this the first micropower precision dual operational amplifier.
The excellent specifications of the individual amplifiers combined with the tight matching and temperature tracking between channels provided high performance in instrumentation amplifier designs. The individual amplifiers feature extremely 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. temperature, non-inverting bias currents, and common-mode rejection ratios.
