Dual general-purpose op-amp in a hermetic ceramic package
The Analog Devices OP213EZ is a dual-channel general-purpose operational amplifier in a hermetic 8-CERDIP package. It delivers a 3.4 MHz gain-bandwidth product and a 1.2 V/µs slew rate, with rail-to-rail output swing. The 4 V to 36 V supply span covers most control-voltage rails.
What the key ratings mean for the BOM
The 3.4 MHz GBW and 1.2 V/µs slew rate are adequate for audio-band filtering, actuator drive loops, and general-purpose ADC buffering. The 100 µV input offset voltage and 240 nA input bias current are moderate. The 40 mA output current per channel can drive a 100 Ω load.
Lifecycle and sourcing reality
The OP213EZ is listed as Active in production, but it is RoHS non-compliant — it contains lead in the solder-dip or die-attach process typical of hermetic ceramic packages. This means it cannot be used on lead-free assembly lines without a waiver. It remains a legitimate choice for military, aerospace, and industrial applications that are exempt from RoHS or that require a hermetic seal. Sourcing is through independent distribution; availability and pricing are confirmed at quote time. No official second-source alternate is recorded, but the ceramic-package requirement limits drop-in equivalents.
