The TL062CPW: For a 1 V peak-to-peak output swing, the slew rate limits the full-power bandwidth to roughly 557 kHz — the amplifier can track sine waves up to that frequency without distortion. Below that, the 1 MHz GBW sets the closed-loop gain bandwidth trade-off: at a gain of 10, the usable signal bandwidth is about 100 kHz. Each of the two channels draws 200 µA of supply current, making this a low-power choice for multi-channel battery-operated or loop-powered applications where the JFET input stage preserves signal integrity from high-impedance sources.
Supply rails, input offset, and bias current — the fit parameters
The 30 pA typical input bias current and 3 mV maximum input offset voltage are well suited for precision DC coupling from high-impedance sensors such as photodiodes, pH probes, or piezoelectric transducers, where bias current errors would otherwise dominate the signal.
