HG741N

HGSEMI · Operational Amplifier · DIP-8

HG741N from HGSEMI, in a DIP-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 OFFSET NULL passive Offset null terminal, connected with a 10 kΩ potentiometer whose wiper goes to V- to trim the input offset voltage (adjustment range ±15 mV typ at VS=±20V).
2 INVERTING INPUT input Inverting input of the op amp, with differential input voltage limited to ±30V and input voltage to ±15V (not exceeding the supply voltage when supplies are below ±15V).
3 NON-INVERTING INPUT input Non-inverting input of the op amp, with differential input voltage limited to ±30V and input voltage to ±15V (not exceeding the supply voltage when supplies are below ±15V).
4 V- power_in Negative supply pin, with the supply voltage limited to ±22V absolute maximum.
5 OFFSET NULL passive Offset null terminal, connected with a 10 kΩ potentiometer whose wiper goes to V- to trim the input offset voltage (adjustment range ±15 mV typ at VS=±20V).
6 OUTPUT output Op amp output with continuous short-circuit protection and typical short-circuit current of 25 mA at TA=25°C.
7 V+ power_in Positive supply pin, with the supply voltage limited to ±22V absolute maximum.
8 NC unconnected No internal connection.

CAD (KiCad official)

  • Symbol: HG741N
  • Footprint: Package_DIP:DIP-8_W7.62mm
  • 3D model: DIP-8 (KiCad packages3D, STEP)
  • 3D model files: hg741n-etched.step / hg741n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hg741n.step / hg741n.glb are the bare package body.
