Wideband op-amp in a hermetic ceramic DIP
Supply current is 6.1 mA, a reasonable draw for the bandwidth on offer. The part operates from ±5 V to ±18 V (10 V to 36 V total supply span), giving flexibility across common analog rails.
Package and assembly — ceramic DIP matters
The OP61FZ comes in an 8-pin ceramic DIP (8-CDIP, 0.300" body width), with the supplier device package listed as 8-CERDIP. This is a hermetic, through-hole package — not a plastic DIP. The ceramic body handles higher-temperature soldering profiles and offers better moisture resistance, but it also means the part is RoHS non-compliant (lead-bearing solder terminals). For designs going into EU markets or any RoHS-regulated jurisdiction, you will need an exemption or a plan to use a compliant alternative. The through-hole mounting suits prototype boards, socketed evaluation, or legacy equipment repair where surface-mount rework is impractical.
The ceramic package helps with thermal cycling reliability compared to plastic, but the 85°C ceiling is the hard limit for junction temperature in continuous operation.
No official successor has been announced.
