The 1 pA input bias current suits it for high-impedance sensor interfaces — photodiode amplifiers, pH probe buffers, or piezoelectric pickups — where bias-current-induced offset would otherwise dominate the error budget. ## Slew rate and output swing — what the 10 V/µs buys you For a 5 V peak-to-peak sine wave, that supports full-power bandwidth around 318 kHz before slew-rate limiting distorts the waveform. ## Package and footprint — SOT-23-5 The OPA743NA/250 comes in a 5-pin SOT-23 package (SC-74A / SOT-753 case code).
