Product details

Single op-amp in a SOT-23-5 — what the ratings tell you

The MAX4165EUK is a single general-purpose operational amplifier from Maxim Integrated, packaged in a 5-pin SOT-23-5 (SC-74A). Supply current is 1.3 mA per amplifier, and it can source or sink 125 mA per channel. Input offset voltage is 350 µV typical, input bias current 50 nA.

Rail-to-rail output and supply range — design fit

The 2.7 V minimum supply means it works directly from a single Li-ion cell or a 3.3 V regulated rail without a boost converter. The 5 MHz GBW and 2V/µs slew rate cover audio-band filtering, sensor buffering, and general signal conditioning — just keep in mind that at higher gains the closed-loop bandwidth drops proportionally, so for gains above 10 you are looking at sub-500 kHz usable bandwidth.

RoHS compliance is listed as non-compliant, which means it may contain lead — verify your assembly's exemption status if you are shipping into RoHS-regulated markets.

Frequently asked questions

Is MAX4165EUK obsolete?

No discontinuation notice has been issued.

Is MAX4165EUK rail-to-rail?

Yes, the output is rail-to-rail, meaning the output voltage can swing close to both supply rails. The input common-mode range is not rail-to-rail — it extends from the negative rail to about 1.1 V below the positive rail.
