Technical details

What this single op-amp delivers

The 2.4 MHz gain-bandwidth product and 0.35 V/µs slew rate place this part in the general-purpose band — fast enough for audio-frequency filtering, slow enough to keep noise gain under control in a 4-20 mA loop or a thermocouple amplifier. The 20 µV input offset voltage and 4 nA input bias current are typical for a precision bipolar stage; you won't need a chopper-stabilized amp unless you're after sub-µV drift. Supply current sits at 550 µA per channel, which is moderate for a 38 V-capable part — not the lowest quiescent draw, but acceptable for most panel-powered designs.
