SBOSA65 July 2021 OPA396
The OPA396 achieves very low input bias current as a results of CMOS inputs and advanced ESD protection circuitry. Input bias current (IB) is primarily a function of the input protection scheme in CMOS input amplifiers. If careful consideration is not taken with the ESD cells, a CMOS input device can exhibit large input bias currents, especially over temperature. The OPA396 achieves excellent input bias current ratings of ±30 pA maximum at 125°C.
