LM7321MFX

Texas Instruments · Precision OpAmps · SOT-23-5

LM7321MFX from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT output Amplifier output. Rail-to-rail output stage; sources up to +65 mA and sinks up to −100 mA. Can swing to within 300 mV of either rail at 15 mA load.
2 V- power_in Negative supply rail. Total V+ to V- supply voltage 2.5 V to 32 V (35 V absolute max). Tie to GND for single-supply operation or to a negative rail for split-supply (e.g. ±15 V).
3 +IN input Noninverting input. Rail-to-rail input common-mode range extending 0.3 V beyond either supply rail. Input voltage must stay within V- − 0.8 V to V+ + 0.8 V (absolute max).
4 -IN input Inverting input. Rail-to-rail input common-mode range extending 0.3 V beyond either supply rail. Differential input voltage limited to ±10 V (absolute max).
5 V+ power_in Positive supply rail. Total V+ to V- supply voltage 2.5 V to 32 V (35 V absolute max). Quiescent current 1.1 mA typical per amplifier.
