HT2171ARZ

HTCSEMI · Operational Amplifier · SOP-8

HT2171ARZ from HTCSEMI, in a SOP-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 Amplifier A output; the voltage range extends to within millivolts of each supply rail.
2 INPA input Non-inverting input of amplifier A; the voltage range can go from 0 to VDD.
3 INNA input Inverting input of amplifier A; it has the same voltage range as INPA, from 0 to VDD.
4 GND power_in Ground pin; connect to the most negative supply, and all GND pads are connected on die.
5 INPB input Non-inverting input of amplifier B; the voltage range can go from 0 to VDD.
6 INNB input Inverting input of amplifier B; it has the same voltage range as INPB, from 0 to VDD.
7 OUTB output Amplifier B output; the voltage range extends to within millivolts of each supply rail.
8 VDD power_in Positive power supply (5V nominal), connected to the positive voltage supply; the operating supply range is 2.5V to 5.5V.

CAD (KiCad official)

  • Symbol: HT2171ARZ
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ht2171arz-etched.step / ht2171arz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht2171arz.step / ht2171arz.glb are the bare package body.
