An op-amp that operates from a single 24 V industrial rail all the way up to a ±45 V split supply covers applications that would otherwise require a high-voltage discrete design. The 2 MHz gain-bandwidth product and 15 V/µs slew rate are sufficient for low-to-moderate frequency signal conditioning: sensor amplification, active filters below 100 kHz, and servo error amplifiers. ## Input and output specs for signal-chain fit Input bias current is 10 pA typical — this suits high-impedance sources like photodiode or pH probe front-ends where bias current drift would otherwise swamp the signal. Input offset voltage is 1.5 mV typical; no auto-zero, but fine for most general-purpose loops. Output drive is 15 mA per channel, enough to swing into a 2 kΩ load at full rail or drive a modest ADC input. ## Package and temperature grade Housed in an 8-SOIC (0.154\", 3.90 mm width) — a standard surface-mount footprint that matches many general-purpose op-amp sockets. Operating temperature range is -25°C to 85°C, covering industrial control cabinets and commercial equipment but not extended automotive or military environments. Supplied in tube packaging; for pick-and-place, plan for tube feeders or request reel packaging if available.","metaTitle":"Texas Instruments OPA445AU Op-Amp, 90V Supply","metaDescription":"Texas Instruments OPA445AU general-purpose op-amp, 20-90V supply, 15V/µs slew rate, 2 MHz GBW, 8-SOIC.
