# OPA552FAKTWT

**Texas Instruments** · Operational Amplifier · TO-263-7

OPA552FAKTWT from Texas Instruments, in a TO-263-7. 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 | Noninverting input; the input voltage range is (V-) - 0.5 V to (V+) + 0.5 V per the absolute maximum ratings. |
| 2 | -IN | input | Inverting input; the input voltage range is (V-) - 0.5 V to (V+) + 0.5 V per the absolute maximum ratings. |
| 3 | NC | unconnected | No internal connection; can be left floating. |
| 4 | V- | power_in | Negative (lowest) power supply; the tab is connected to this supply. |
| 5 | V+ | power_in | Positive (highest) power supply; the device supports ±4 V to ±30 V (8 V to 60 V total supply span). |
| 6 | Out | output | Amplifier output; rated for 200 mA continuous and current-limited, with safe operating area limits given in the SOA curves. |
| 7 | Flag | output | Thermal shutdown indicator; outputs a current to alert the user when thermal shutdown has occurred. |
| 8 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
