Quad general-purpose op-amp — 28 MHz GBW, 12 V/µs
The Analog Devices LT1214CS#PBF is a quad general-purpose operational amplifier in the LT® series. Each of the four channels draws 3.4 mA total supply current, making it a power-efficient choice for multi-channel signal conditioning in industrial control, sensor front-ends, and active filter stages.
Supply range and temperature — fits industrial rails
The supply span from 2.5 V to 36 V covers single lithium-cell designs up to 24 V industrial buses.
28 MHz GBW — what it means for signal chain
The 28 MHz gain-bandwidth product supports closed-loop gains up to 10 while maintaining a bandwidth above 2.8 MHz, adequate for ADC drivers, anti-aliasing filters, and audio processing. The 12 V/µs slew rate keeps large-signal distortion low up to roughly 1 MHz output swings. Input offset voltage is 150 µV typical, and input bias current is 90 nA — fine for precision DC coupling but watch for offset drift if the source impedance exceeds 10 kΩ.
Output drive and package
Each amplifier can source or sink 50 mA, enough to drive moderate loads like a 100 Ω line or a small relay coil directly. Supplied in Tube, not tape-and-reel, so plan for pick-and-place feeder change if your line is reel-only.
