What are the differences between the A3212 and A3210?
The A3212 is an improvement to the A3210 in power consumption, magnetic switch points, and offers an extended temperature range as referenced in question 6. The max supply current of the 3212 is lower at 10 µA at 2.75 V, versus the 3210 which is 25 µA. The switch points are tighter with a BOP of ±55 Gauss and BRP of ±10 Gauss compared to the A3210 with a BOP of ±60 Gauss and BRP of ±5 Gauss. The switch point change allows for operation with a weaker magnetic field while compensating for magnetic noise created by such things as a cellular phone speaker or computer hard drive. The changes make the new device more attractive to applications concerned with battery life and switch point sensitivity.
