Its input bias current of 1 pA is the standout spec for high-impedance sources — think photodiode transimpedance amplifiers, pH probe buffers, or any sensor where nanoamp-level leakage would corrupt the measurement.
It is offered in Tape & Reel for production reels and Cut Tape for prototyping or low-volume builds — both options are available through our sourcing desk.
The TLC2272AIDR is the 8-SOIC surface-mount variant in Tape & Reel, while the TLC2272IP is the 8-PDIP through-hole version. Electrically they share the same CMOS op-amp core — 2.25 MHz GBW, 3.6 V/µs slew rate, 1 pA input bias — so the choice is purely a board-assembly and footprint decision.
