The 4.5 V minimum supply means this part runs cleanly on a 5 V rail with margin, and the 36 V maximum allows ±18 V dual-supply operation. At 220 µA quiescent current, it fits into low-power signal chains where every microamp counts — think battery-backed sensor interfaces or loop-powered transmitters. The 60 mA output current per channel gives enough drive for moderate loads like ADC inputs or reference buffers, though it is not a power-stage driver. ## Slew rate and bandwidth — what the numbers mean The 1 MHz GBW sets the closed-loop bandwidth for a given gain: at a gain of 10, expect roughly 100 kHz of usable bandwidth. The 3.5 V/µs slew rate supports full-power signals up to about 55 kHz at 10 V output swing — fine for audio, slow ADC drivers, or control loops, but not for video or fast data acquisition. The 5 pA input bias current is a strong point for high-impedance sources like photodiodes or pH probes, where bias current error would otherwise dominate the offset. The 2K5 suffix indicates a 2500-unit reel on Tape & Reel; the part is also available in Cut Tape for smaller quantities.","metaTitle":"OPA137UA/2K5 General Purpose Op-Amp, 1 MHz GBW, 8-SOIC","metaDescription":"Texas Instruments OPA137UA/2K5 single general-purpose op-amp, 1 MHz GBW, 3.5 V/µs slew rate, 220 µA supply, 4.5–36 V supply, -40 to 85°C, 8-SOIC.
