# ISO224BDWV

**Texas Instruments** · Special Purpose Amplifiers · SOIC-8-300mil

ISO224BDWV from Texas Instruments, in a SOIC-8-300mil. 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 | VCAP | passive | Supply decoupling capacitor pin; connect a 0.22-µF capacitor between this pin and the high-side analog ground (GND1). |
| 2 | IN | input | Analog input, specified linear full-scale ±12 V (IN to GND1), clipping above ±13.8 V, absolute maximum ±15 V, and input current limited to ±10 mA continuous. |
| 3 | VDD1 | power_in | High-side power supply, 4.5 V to 18 V (VDD1 to GND1); decoupling per the Power Supply Recommendations section. |
| 4 | GND1 | power_in | High-side analog ground, reference for VDD1, the IN input and the VCAP capacitor. |
| 5 | GND2 | power_in | Low-side analog ground, reference for VDD2 and the OUTP/OUTN outputs. |
| 6 | OUTN | output | Inverting analog output, limited to GND2 - 0.3 V to VDD2 + 0.3 V. |
| 7 | OUTP | output | Noninverting analog output, limited to GND2 - 0.3 V to VDD2 + 0.3 V. |
| 8 | VDD2 | power_in | Low-side power supply, 4.5 V to 5.5 V (VDD2 to GND2); decoupling per the Power Supply Recommendations section. |
