1 MHz CMOS dual op-amp, 45 µA per channel
The OPA2348AIDR: Supply current is 45 µA per channel, making it suited for battery-powered or loop-powered applications where every microamp counts.
Input bias and offset — the signal-chain floor
Input bias current is 0.5 pA typical — this is a CMOS-input amplifier, so the bias current stays negligible across temperature, which matters for high-impedance sensor front-ends like photodiode transimpedance stages or pH probe buffers. Input offset voltage is 1 mV maximum, which sets the DC accuracy floor for the gain stage; a gain-of-100 circuit sees a 100 mV output offset before any signal.
RoHS3 compliant per the manufacturer's declaration, with no exemptions that would require a waiver for EU or UKCA markets.
