Allegro MicroSystems, LLC · Angle, Linear Position Sensors · TSSOP-8

A1330LLETR-P-T from Allegro MicroSystems, LLC, 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 VCC power_in Device power supply, specified at 4.5 to 5.5 V, and also serves as the Manchester communication input pin.
2 VOUT bidirectional Angle output (analog or PWM for this PWM-output variant), which also carries the Manchester output during serial communication and receives EEPROM programming pulses.
3 NC unconnected Not connected; the datasheet says it must be tied to GND for optimum ESD performance.
4 GND power_in Ground connection for the device.
5 NC unconnected Not connected; the datasheet says it must be tied to GND for optimum ESD performance.
6 NC unconnected Not connected; the datasheet says it must be tied to GND for optimum ESD performance.
7 NC unconnected Not connected; the datasheet says it must be tied to GND for optimum ESD performance.
8 NC unconnected Not connected; the datasheet says it must be tied to GND for optimum ESD performance.
