Rail-to-rail output swing lets the amplifier drive the full supply range into the load — useful when the ADC reference or comparator threshold sits near the rails and every millivolt of headroom matters. Each channel draws 850 µA supply current, keeping the total quiescent draw under 1.7 mA for the pair — a fit for multi-channel battery-powered signal chains where the op-amp budget competes with the sensor bias and ADC power. ## Parametric fit for precision analog front-ends Input bias current is 0.2 pA typical — the CMOS input stage keeps the error term negligible for high-impedance sources like photodiode transimpedance stages or pH probe buffers, where a bipolar input's nanoamp bias would shift the DC operating point. Supply span from 2.5 V to 5.5 V covers single 3.3 V or 5 V rails commonly used in portable instrumentation and sensor interfaces, with 50 mA output drive per channel sufficient to swing into the feedback network and a moderate ADC input. Input offset voltage is 2 mV maximum — adequate for 8- to 10-bit signal paths without autozero; for 12-bit systems the offset can be calibrated out in firmware or trimmed at the board level. ## Package, temperature grade, and compliance Housed in an 8-SOIC (0.154\", 3.90 mm width) with supplier device package 8-SOIC — the same footprint as the industry-standard SO-8, so no board spin from a prior SO-8 op-amp layout. Rated for -40°C to +85°C industrial temperature range, covering most indoor and outdoor equipment enclosures that do not see under-hood or engine-bay extremes.","metaTitle":"Texas Instruments OPA2343UA/2K5 CMOS Op-Amp, 5.5MHz","metaDescription":"Texas Instruments OPA2343UA/2K5 dual CMOS op-amp, 5.5 MHz GBW, 6V/µs slew rate, rail-to-rail output, 8-SOIC, RoHS3.
