High speed precision comparator in a hermetic can
The CMP05CJ is a high speed precision comparator from Analog Devices, built for applications where propagation delay and input offset stability matter — think fast overvoltage detection, zero-crossing triggers, or window comparators in test equipment and industrial control. Housed in a TO-99-8 metal can (through hole), the hermetic package seals the die against moisture and thermal cycling, which is why you still see this footprint in avionics, ATE, and high-reliability designs where a plastic SOIC would drift out of spec over temperature.
Active production and compliance
Note the RoHS status: marked non-compliant. If your assembly line requires RoHS-10 exemption or you are stocking a leaded solder rework station, this is fine; for full RoHS compliance, a tin-plated alternative would need a different order code.
