60 MHz GBP at 1 mA — the power-efficiency anchor
The Analog Devices LT6220IS5#TRPBF is a single general-purpose op-amp that delivers a 60 MHz gain-bandwidth product while drawing only 1 mA of supply current. That combination — 60 MHz GBP at 1 mA — is the headline trade-off that makes this part a candidate for active filters, ADC drivers, or signal-conditioning stages where every milliamp in the power budget is accounted for. Supply span runs from 2.2 V up to 12.6 V, covering single Li-ion through industrial 12 V rails. Input offset voltage is specified at 700 µV, input bias current at 250 nA — adequate for moderate-impedance sensor interfaces.
Rail-to-rail output and supply flexibility
The rail-to-rail output stage is the key enabler for single-supply designs: it swings within millivolts of each rail, so a 3.3 V supply yields nearly the full 3.3 Vpp output swing. That matters when driving an ADC input or a downstream comparator that needs the full signal range. The supply voltage range of 2.2 V to 12.6 V means the same part can be used across a 3.3 V portable product and a 12 V industrial sensor interface without a respin.
