OPA2340MM

HGSEMI · Precision Op Amps · MSOP-8

OPA2340MM from HGSEMI, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTA output Output of amplifier A, rail-to-rail.
2 INA- input Inverting input of amplifier A; keep within VSS-0.5V to VDD+0.5V (abs max).
3 INA+ input Non-inverting input of amplifier A; keep within VSS-0.5V to VDD+0.5V (abs max).
4 VSS power_in Negative supply or ground; single supply 1.8V to 5.5V total, bypass with 0.1µF for dual supply.
5 INB+ input Non-inverting input of amplifier B; keep within VSS-0.5V to VDD+0.5V (abs max).
6 INB- input Inverting input of amplifier B; keep within VSS-0.5V to VDD+0.5V (abs max).
7 OUTB output Output of amplifier B, rail-to-rail.
8 VDD power_in Positive supply, 1.8V to 5.5V operating (7.5V abs max); place a 0.1µF ceramic capacitor close to the pin.

CAD (KiCad official)

  • Symbol: OPA2340MM
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: opa2340mm-etched.step / opa2340mm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa2340mm.step / opa2340mm.glb are the bare package body.
