OPA860IDR

Texas Instruments · Special Purpose Amplifiers · SOIC-8

OPA860IDR from Texas Instruments, in a SOIC-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 IQ Adjust passive External resistor on this pin sets the OTA transconductance, trading quiescent current against bandwidth and gain; the datasheet test conditions use RADJ = 250Ω.
2 E bidirectional OTA emitter terminal, a low-impedance input/output; the datasheet specifies E-input resistance of 10.5 Ω min at +25°C and 12.5 Ω min at 0°C to -40°C.
3 B input OTA base terminal, a high-impedance input with a B-input voltage range of ±4.2 V typ (±3.6 V min over temperature).
4 V− power_in Negative supply rail, −5 V in the datasheet operating configuration; absolute maximum power supply is ±6.5 VDC.
5 In input Input of the closed-loop unity-gain voltage buffer.
6 Out output Output of the closed-loop unity-gain voltage buffer, rated for 60 mA output current.
7 V+ power_in Positive supply rail, +5 V in the datasheet operating configuration; absolute maximum power supply is ±6.5 VDC.
8 C output OTA collector terminal, the bipolar current output of the transconductance amplifier.

CAD (KiCad official)

  • Symbol: OPA860IDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: opa860idr-etched.step / opa860idr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa860idr.step / opa860idr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (36 pp, sha256 1c3e4e6a2a099e37, retrieved 2026-10-08, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
