Samples are no longer available. Date of status change: December 5, 2016.Deadline for receipt of LAST TIME BUY orders: August 30, 2017
Recommended Substitutions: A1308 For existing customer transition, and for new customers or new applications, please contact the factory.
The A1301 and A1302 are continuous-time, ratiometric, linear Hall-effect sensor ICs. They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. These devices have a quiescent output voltage that is 50% of the supply voltage. Two output sensitivity options are provided: 2.5 mV/G typical for the A1301, and 1.3 mV/G typical for the A1302.
The Hall-effect integrated circuit included in each device includes a Hall sensing element, a linear amplifier, and a CMOS Class A output structure. Integrating the Hall sensing element and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals.
High precision in output levels is obtained by internal gain and offset trim adjustments made at end-of-line during the manufacturing process.
These features make the A1301 and A1302 ideal for use in position sensing systems, for both linear target motion and rotational target motion. They are wellsuited for industrial applications over extended temperature ranges, from -40°C to 125°C.
