# APS00B

**JSMSEMI** · Position Sensors · SOP-8

APS00B from JSMSEMI, 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 | B- | output | Negative output of bridge B (AMR Wheatstone bridge), which together with B+ carries the sine-channel signal VoutB = (Vamp/2)·sin(2α) for clockwise field rotation. |
| 2 | A- | output | Negative output of bridge A, which together with A+ carries the cosine-channel signal VoutA = (Vamp/2)·cos(2α) for clockwise field rotation. |
| 3 | NC | unconnected | Not connected; the datasheet lists this pin as NC with no function. |
| 4 | Vs | power_in | Supply voltage pin; the absolute maximum rating is -12 V to 12 V and the electrical characteristics are specified at VS = 5.0 V to 12.0 V. |
| 5 | B+ | output | Positive output of bridge B, paired with B- to provide the sine-channel signal. |
| 6 | A+ | output | Positive output of bridge A, paired with A- to provide the cosine-channel signal. |
| 7 | NC | unconnected | Not connected; the datasheet lists this pin as NC with no function. |
| 8 | GND | power_in | Ground reference pin for the sensor. |
