# OPA170AIDRLT

**Texas Instruments** · Operational Amplifier · SOT-553-5

OPA170AIDRLT from Texas Instruments, in a SOT-553-5. 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 | IN+ | input | Positive (non-inverting) input; the common-mode range runs from 100 mV below V- to 2 V below V+ and can reach 100 mV above V+ with degraded performance. |
| 2 | V- | power_in | Negative (lowest) supply; total supply (V+ - V-) must be 2.7 V to 36 V. |
| 3 | IN- | input | Negative (inverting) input; input current should be limited to 10 mA. |
| 4 | OUT | output | Amplifier output; rail-to-rail, stable with capacitive loads up to 300 pF. |
| 5 | V+ | power_in | Positive (highest) supply; total supply (V+ - V-) must be 2.7 V to 36 V, with a 0.1 µF bypass capacitor placed close to the pin. |

## CAD (KiCad official)

- Symbol: `OPA170AIDRLT`
- Footprint: `Package_TO_SOT_SMD:SOT-553`
- 3D model: SOT-553-5 (KiCad packages3D, STEP)
- 3D model files: `opa170aidrlt-etched.step` / `opa170aidrlt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa170aidrlt.step` / `opa170aidrlt.glb` are the bare package body.
