Pin Configuration
ZXCT1008FTA – SOT-23 Pinout
| Pin Number | Pin Name | Type | Description |
|---|---|---|---|
| 1 | I_OUT | O | Output current (proportional to sensed current) |
| 2 | V_SENSE+ | I | Positive sense input |
| 3 | V_SENSE- | I | Negative sense input |
Notes
- Pin 4 (GND/VSS) is not shown in the diagram but is typically present in SOT-23 packages. Verify against the full datasheet if a ground pin is required for your application.
- The device is a current-sense amplifier with a single output pin (I_OUT) and differential sense inputs (V_SENSE+, V_SENSE-).
