Dual CMOS op-amp for signal conditioning chains
Supply span runs from 3.5 V to 12 V, with each channel drawing 1.1 mA quiescent current.
The 7 MHz gain-bandwidth product sets the usable closed-loop gain range: at a gain of 10, the -3 dB bandwidth drops to roughly 700 kHz, enough for audio-band processing or 100 kHz sensor excitation. The 10 V/µs slew rate supports full-output swings up to about 350 kHz without slew-induced distortion, which matters when driving the input of a 12-bit SAR ADC at moderate sampling rates. Input bias current of 1 pA keeps DC errors low in high-impedance applications like photodiode transimpedance amplifiers or pH probe buffers. The 1.5 mV input offset voltage is typical for this class; designs needing tighter offset should budget for a trim or select a precision-grade sibling.
Housed in an 8-VSSOP (3.00 mm width) surface-mount package, the OPA2743EA/250 fits dense PCB layouts. ROHS3 compliant per the listing.
For dual-sourcing resilience, the OPA4374AIPWT is a four-channel CMOS alternative with 6.5 MHz GBW and 5 V/µs slew rate, though in a different package and temperature range.
