TAS2143-AAAA from TDK, in a TSSOP-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 | -Sin | output | Negative leg of the differential sine output of the TMR bridge, which for the TAS2143-AAAA gives 3.0 Vp-p differential output at 5 V supply (Vout typ. 0.6 V/V per Vcc at 30 mT). |
| 2 | Vsin | power_in | Supply pin for the sine bridge, specified for 3 V to 5.5 V recommended operation (typ. 5 V) with a 6.5 V absolute maximum. |
| 3 | +Sin | output | Positive leg of the differential sine output of the TMR bridge, valid across the 20 mT to 80 mT nominal magnetic field range. |
| 4 | Gsin | power_in | Ground pin for the sine bridge. |
| 5 | +Cos | output | Positive leg of the differential cosine output of the TMR bridge, valid across the 20 mT to 80 mT nominal magnetic field range. |
| 6 | Vcos | power_in | Supply pin for the cosine bridge, specified for 3 V to 5.5 V recommended operation (typ. 5 V) with a 6.5 V absolute maximum. |
| 7 | -Cos | output | Negative leg of the differential cosine output of the TMR bridge, which for the TAS2143-AAAA gives 3.0 Vp-p differential output at 5 V supply (Vout typ. 0.6 V/V per Vcc at 30 mT). |
| 8 | Gcos | power_in | Ground pin for the cosine bridge. |
