Its 4 MHz -3 dB bandwidth paired with a 14 V/µs slew rate means it tracks fast transients without slew-induced distortion — useful for digitizing motor-phase currents or sensor bridge outputs where the signal edge rate exceeds what a general-purpose op-amp can follow. ## Supply range, offset, and output drive Runs on a single or split supply from 8 V to 36 V total — the wide span lets it share the same ±15 V or 24 V rail already on the board without a secondary regulator. Input offset voltage is trimmed to 100 µV typical, which keeps the DC error below 0.1 % on a 100 mV shunt signal without a software calibration step. Output can source or sink 60 mA per channel — enough to drive the input of a successive-approximation ADC directly or a twisted-pair cable through a 50 Ω series resistor. Quiescent supply current is 2.4 mA per amplifier, so the thermal budget in a dense 8-SOIC layout stays low even with all channels active. ## Package, temperature grade, and compliance Housed in an 8-SOIC with 0.154-inch body width and 3.90 mm pitch — the standard SOIC-8 footprint that routes on a two-layer board without via fan-out. Rated for -40°C to 85°C ambient, covering industrial enclosures and outdoor telecom cabinets where the internal air temperature stays below 70°C. Supplied in Tape & Reel (2,500 units) or Cut Tape — the reel format suits automated pick-and-place with no carrier-tape splice required.","metaTitle":"Texas Instruments INA157U/2K5 Differential Op-Amp, 14V/µs","metaDescription":"Texas Instruments INA157U/2K5 differential amplifier, 4 MHz bandwidth, 14V/µs slew rate, 8-SOIC.
