OPA140AIDR

Texas Instruments · Precision OpAmps · SOIC-8

OPA140AIDR from Texas Instruments, in a SOIC-8. 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 NC unconnected No internal connection. Can be left floating.
2 -IN input Inverting input of the op-amp. Diode-clamped to the supply rails; keep input current below 10 mA. Rail-to-rail input range includes V-.
3 +IN input Noninverting input of the op-amp. Diode-clamped to the supply rails; keep input current below 10 mA. Rail-to-rail input range includes V-.
4 V- power_in Negative (lowest) power supply. Connect to ground for single-supply operation (4.5 V to 36 V on V+) or to a negative rail for dual-supply operation (±2.25 V to ±18 V).
5 NC unconnected No internal connection. Can be left floating.
6 OUT output Op-amp output. Rail-to-rail output swing; short-circuit protected (short to Vs/2 continuous, one amplifier per package).
7 V+ power_in Positive (highest) power supply. Total supply Vs = (V+) - (V-) must not exceed 40 V. Typical quiescent current 1.8 mA (2 mA max).
8 NC unconnected No internal connection. Can be left floating.
