HA1001EM

QH MICRO-E · Differential OpAmps · MSOP-8

HA1001EM from QH MICRO-E, 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 -IN input Negative (inverting) input of the differential amplifier.
2 VOCM input Common-mode control pin; an external reference voltage sets the output common-mode level.
3 VCC power_in Positive supply, 3.3V to 5V single supply (±1.65V to ±2.5V dual), absolute maximum 6V.
4 +OUT output Positive (non-inverting) output of the differential amplifier.
5 -OUT output Negative (inverting) output of the differential amplifier.
6 GND power_in Chip ground; connect to the negative supply when using dual supplies.
7 PD input Enable/power-down pin (name not printed in the table); must be tied high for normal operation, enabled above 2.2V and power-down below 1.9V.
8 +IN input Positive (non-inverting) input of the differential amplifier.

CAD (KiCad official)

  • Symbol: HA1001EM
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: ha1001em-etched.step / ha1001em-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ha1001em.step / ha1001em.glb are the bare package body.
