5.5 MHz GBW, rail-to-rail, 750 µA — the signal-chain workhorse
Quiescent current is 750 µA per amplifier — low enough for battery-operated instrumentation panels and portable data loggers, yet the 5.5 MHz GBW supports audio-band filtering and moderate-speed control loops.
Supply span and temperature grade — industrial and portable fit
Input bias and offset — precision for the class
With 0.2 pA input bias current and 150 µV input offset voltage, the OPA340UA/2K5G4 handles high-impedance sources (pH probes, photodiode transimpedance stages) without adding significant DC error. The 50 mA output current per channel drives moderate loads — think reference buffers or line drivers — without a separate buffer stage.
