Allegro's A1318 and A1319 are factory one-time programmable (OTP-ROM) linears that eliminate the need for customers to optimize/program the devices for their finished sensor assemblies. The A1318 and A1319 devices build on the flexibility and economic competitiveness of the A1381 / 2 / 3 / 4 devices; however, they are targeted towards 3.3 V supply-rail applications.

The A1318 and A1319 architecturally have the ability to support a magnetic input sensitivity range of 1.32 mV/G to 2.64 mV/G, and 2.64 mV/G to 5.94 mV/G, respectively. However, the A1318 / 19 devices initially being released to market are factory programmed to specific magnetic input sensitivity levels, via unique CASs for specific customer programming requirements.
