This datasheet also covers the A1220 variant, as both devices belong to the same chopper-stabilized precision hall-effect latches family and are provided as variant models within a single manufacturer datasheet.
General Description
The A1220, A1221, A1222, and A1223 Hall-effect sensor ICs are extremely temperature-stable and stress-resistant devices especially suited for operation over extended temperature ranges to 150°C.
Note: Below is a high-fidelity text extraction (approx. 800 characters) for
