JAJSGP3A December 2018 – December 2019 OPA462
PRODUCTION DATA.
When operating the OPA462 with high supply voltages, parasitic leakages may occur between the inputs and the supplies. This effect is most noticeable at the noninverting input, +IN, when the input common-mode voltage is high compared to the negative supply voltage, V–. To minimize this leakage, place guard tracing, driven at the same voltage as the input signal, alongside the input signal traces and pins.
