LM348DR from Texas Instruments, in a SOIC-14. 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 1OUT output Output of op-amp 1. Class-AB output stage, short-circuit protected, typical peak output swing +/-13 V into >=10 kOhm at +/-15 V supplies.
2 1IN- input Inverting input of op-amp 1. High-impedance differential input (typ 2.5 MOhm), input bias current 30 nA typ, input offset current 4 nA typ.
3 1IN+ input Non-inverting input of op-amp 1. Common-mode input range typ +/-12 V at +/-15 V supplies.
4 VCC+ power_in Positive supply voltage. LM348 absolute max +18 V; recommended operating +4 V to +18 V. Shared by all four amplifiers.
5 2IN+ input Non-inverting input of op-amp 2. Common-mode input range typ +/-12 V at +/-15 V supplies.
6 2IN- input Inverting input of op-amp 2. High-impedance differential input, typ 2.5 MOhm.
7 2OUT output Output of op-amp 2. Class-AB output stage, short-circuit protected.
8 3OUT output Output of op-amp 3. Class-AB output stage, short-circuit protected.
9 3IN- input Inverting input of op-amp 3. High-impedance differential input, typ 2.5 MOhm.
10 3IN+ input Non-inverting input of op-amp 3. Common-mode input range typ +/-12 V.
11 VCC- power_in Negative supply voltage. LM348 absolute max -18 V; recommended operating -4 V to -18 V. Shared by all four amplifiers.
12 4IN+ input Non-inverting input of op-amp 4. Common-mode input range typ +/-12 V.
13 4IN- input Inverting input of op-amp 4. High-impedance differential input, typ 2.5 MOhm.
14 4OUT output Output of op-amp 4. Class-AB output stage, short-circuit protected.

CAD (KiCad official)

  • Symbol: LM348DR
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: lm348dr-etched.step / lm348dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm348dr.step / lm348dr.glb are the bare package body.
