OPA189IDBVT

Texas Instruments · Precision Op Amps · SOT-23-5

OPA189IDBVT from Texas Instruments, in a SOT-23-5. 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 OUT output Amplifier output (OPA189 DBV pin 1 per Table 6-1); the device has a rail-to-rail output stage.
2 V- power_in Negative power supply, the lowest potential on the device; the operating supply is 4.5 V to 36 V single-supply or ±2.25 V to ±18 V dual-supply.
3 +IN input Non-inverting input; the common-mode voltage must stay between (V-) - 0.5 V and (V+) + 0.5 V and input current is limited to ±10 mA per the absolute maximum ratings.
4 -IN input Inverting input; the common-mode voltage must stay between (V-) - 0.5 V and (V+) + 0.5 V and input current is limited to ±10 mA per the absolute maximum ratings.
5 V+ power_in Positive power supply, the highest potential on the device; absolute maximum supply is 40 V single-supply or ±20 V dual-supply.

CAD (KiCad official)

  • Symbol: OPA189IDBVT
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: opa189idbvt-etched.step / opa189idbvt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa189idbvt.step / opa189idbvt.glb are the bare package body.
