This bandwidth ceiling suits it for filtering and amplification in sensor signal chains where the signal of interest sits below a few tens of kilohertz — thermocouple conditioning, strain-gauge bridges, or photodiode front-ends with moderate data rates. Supply current is 275 µA typical (cites:), placing it in the micropower class. For a battery-powered data logger or a loop-powered 4-20 mA transmitter, the quiescent draw does not dominate the power budget. Input bias current is 12 nA (cites:), and input offset voltage is 70 µV (cites:) — both adequate for non-precision DC-coupled stages where a few millivolts of offset are acceptable. Output drive capability is 22 mA per channel (cites:), enough to swing a 0-10 V signal into a 500 Ω load or drive the analog input of a typical microcontroller ADC without a separate buffer. The supply span runs from 2.7 V to 36 V (cites:,), so the same part works on a 3.3 V logic rail or a ±15 V industrial supply without a regulator change. ## Industrial temperature grade and package fit Operating temperature range is -40°C to 125°C (cites:), covering the full industrial and automotive under-hood ambient envelope. The 8-SOIC package (0.154-inch body width, 3.90 mm) (cites:) with supplier device package 8-SOIC (cites:) is a standard surface-mount footprint shared by thousands of op-amp and logic parts — no board spin for a package change. Delivered in bulk tube (cites:), not tape-and-reel; factor this into your pick-and-place feeder setup if the line expects reeled parts. ## Lifecycle and compliance Texas Instruments lists the OPA234U-TI as Active (cites:) and ROHS3 Compliant (cites:). For a BOM line that needs a general-purpose op-amp in an SOIC-8 footprint, this part is a straightforward, in-production choice — no last-time-buy planning required.","metaTitle":"Texas Instruments OPA234U-TI General Purpose Op-Amp, 350 kHz","metaDescription":"Texas Instruments OPA234U-TI general purpose op-amp, 350 kHz GBW, 0.2 V/µs slew rate, 275 µA supply, -40°C to 125°C, 8-SOIC.
