# TP358-SR

**UMW** · Operational Amplifier · SOP-8

TP358-SR from UMW, in a SOP-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 | Out A | output | Output of amplifier A, rail-to-rail output; absolute maximum output current is ±40mA and output short-circuit duration is indefinite. |
| 2 | -In A | input | Inverting input of amplifier A; input voltage must stay between V- − 0.1 V and V+ + 0.1 V, and input current is limited to ±10mA (ESD diodes to each supply; limit current to below 10mA if the input exceeds the supply by more than 300mV). |
| 3 | +In A | input | Non-inverting input of amplifier A; input voltage must stay between V- − 0.1 V and V+ + 0.1 V, and input current is limited to ±10mA (ESD diodes to each supply; limit current to below 10mA if the input exceeds the supply by more than 300mV). |
| 4 | -VS | power_in | Negative power supply (V-); the datasheet gives a 2.1V to 6.0V supply range and a 6.6V absolute maximum supply voltage across V+ to V-. |
| 5 | +In B | input | Non-inverting input of amplifier B; input voltage must stay between V- − 0.1 V and V+ + 0.1 V, and input current is limited to ±10mA (ESD diodes to each supply; limit current to below 10mA if the input exceeds the supply by more than 300mV). |
| 6 | -In B | input | Inverting input of amplifier B; input voltage must stay between V- − 0.1 V and V+ + 0.1 V, and input current is limited to ±10mA (ESD diodes to each supply; limit current to below 10mA if the input exceeds the supply by more than 300mV). |
| 7 | Out B | output | Output of amplifier B, rail-to-rail output; absolute maximum output current is ±40mA and output short-circuit duration is indefinite. |
| 8 | +VS | power_in | Positive power supply (V+); the datasheet gives a 2.1V to 6.0V supply range and a 6.6V absolute maximum supply voltage across V+ to V-. |

## CAD (KiCad official)

- Symbol: `TP358-SR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `tp358-sr-etched.step` / `tp358-sr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tp358-sr.step` / `tp358-sr.glb` are the bare package body.
