What the 700 kHz bandwidth and 1 pA bias tell you
The AD545KH is a single-channel general-purpose op-amp from Analog Devices in a through-hole TO-99-8 metal can. Its 700 kHz bandwidth and 1 pA input bias current place it squarely in the FET-input class — negligible loading on high-impedance sources like photodiodes, pH electrodes, or piezoelectric sensors. Supply current of 800 µA keeps the thermal footprint low in a metal-can package that sinks heat to the board. The 36 V maximum supply span (10 V minimum) gives headroom for ±15 V industrial rails or single 12 V/24 V systems.
Package reality: TO-99-8 metal can, through hole
This is a through-hole part in a TO-99-8 metal can — no SMT option. The metal can provides good shielding and thermal conduction, but the package is larger and harder to automate than an SOIC or MSOP. Bulk shipping (tube or tray) means manual handling or feeder changeover on the line. If your board is all SMT, this part adds a separate insertion step.
Note that RoHS compliance is listed as non-compliant, so this part is not lead-free; verify your assembly process accepts tin-lead solder.
