HT741ARZ

HTCSEMI · Operational Amplifier · SOP-8

HT741ARZ from HTCSEMI, in a SOP-8. 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 OFFSET_NULL input Offset null pin used with pin 5 and an external trim potentiometer (typ. 10 kΩ to V-) to eliminate the input offset voltage and balance the input stage.
2 INVERTING_INPUT input Inverting signal input (-) of the operational amplifier. Input common-mode range ±12 V (typ) at Vcc = ±15 V.
3 NONINVERTING_INPUT input Non-inverting signal input (+) of the operational amplifier. Input common-mode range ±12 V (typ) at Vcc = ±15 V.
4 V- power_in Negative supply voltage. Operating range ±5 V to ±18 V (absolute maximum ±20 V). Typical quiescent supply current 2.8 mA.
5 OFFSET_NULL input Offset null pin used with pin 1 and an external trim potentiometer (wiper to V-) to eliminate the input offset voltage.
6 OUTPUT output Amplified signal output. Output swing typ. ±12 V into 10 kΩ, ±10 V into 2 kΩ; short-circuit current typ. 10 mA; slew rate typ. 0.25 V/µs.
7 V+ power_in Positive supply voltage. Operating range ±5 V to ±18 V (absolute maximum ±20 V). Typical quiescent supply current 2.8 mA.
8 NC unconnected No connect. Should be left floating.

CAD (KiCad official)

  • Symbol: HT741ARZ
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ht741arz-etched.step / ht741arz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht741arz.step / ht741arz.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: HTCSEMI datasheet (5 pp, sha256 7e17a5b249ca193a, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
