The CMOS inputs draw only 0.5 pA of bias current, so high-impedance sensor signals (thermistors, photodiodes, pH probes) are not loaded down — a real advantage when the trace runs across a noisy PCB. ## Output drive and input offset Each output can source or sink 10 mA. Input offset voltage is trimmed to 1 mV.","metaTitle":"OPA4348AIDR CMOS Op-Amp, 1 MHz GBW, Rail-to-Rail, 14-SOIC","metaDescription":"TI OPA4348AIDR quad CMOS op-amp, 1 MHz GBW, 0.5 V/µs slew rate, rail-to-rail output, 2.1-5.5 V supply, -40 to 125°C.
