Datasheet A1321, A1322, A1323 (Allegro) - 3

A1321, A1322, Ratiometric Linear Hall Effect Sensor ICs and A1323 for High-Temperature Operation Description (continued)
recoverability after temperature cycling. Having the Hall element The A132X family is provided in a 3-pin single in-line package and an amplifier on a single chip minimizes many problems normally (UA) and a 3-pin surface mount package (LH). Each package is associated with low-level analog signals. available in a lead (Pb) free version (suffix, –T) , with a 100% matte tin plated leadframe. Output precision is obtained by internal gain and offset trim adjustments made at end-of-line during the manufacturing process.

The product is approaching end of life. Within a minimum of 6 months, the device will enter its final, Last Time Buy, order phase. Status change: January 31, 2011. Suggested replacements: for the A1321ELHLT-T and the A1321LLHLT-T use the A1324LLHLX-T, for the A1322LLHLT-T use the A1325LLHLX-T, and for the A1323LLHLT-T use the A1326LLHLX-T. 3Variant is in production but has been determined to be NOT FOR NEW DESIGN. This classification indicates that sale of the variant is currently restricted to existing customer applications. The variant should not be purchased for new design applications because obsolescence in the near future is probable. Samples are no longer available. Status change: January 31, 2011.
