It offers a 3 V/µs slew rate, 50 kHz -3 dB bandwidth, and 25 pA input bias current, making it suited for precision low-frequency analog signal conditioning where low input current drift and high input impedance matter. The dual-channel configuration saves board space in multi-channel integrator, sample-and-hold, or photodiode amplifier stages. ## Package and rework – the TO-99 metal can This is a through-hole part in a TO-99-8 metal can. The hermetic seal protects the die from moisture and contaminants. Rework is straightforward with a standard soldering iron. The metal case also acts as a heat spreader, though at 25 mA output per channel thermal rise is minimal at room temperature. However, it is marked RoHS non-compliant – the TO-99 can uses lead-bearing solder or plating. If your assembly line is RoHS-exempt (military, aerospace, medical implant, or high-reliability industrial), this is not a blocker. For commercial lead-free reflow, you will need to verify the exemption or find a tin-plated equivalent.","metaTitle":"AD642LH Dual JFET Op-Amp, 3 V/µs Slew Rate, TO-99-8","metaDescription":"AD642LH dual JFET op-amp: 3 V/µs slew rate, 50 kHz bandwidth, 25 pA input bias, TO-99-8 metal can.

The AD712KNZ is significantly faster – 4 MHz bandwidth and 20 V/µs slew rate – but shares the same 25 pA input bias current and 500 µV offset voltage class. For a surface-mount alternative, the AD712JRZ offers the same specs in an SOIC-8 package. Neither is a pin-for-pin drop-in due to different package outlines."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/AD642LH","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/AD642LH when reusing this data.
