Description (continued)
The A3241 and A3242 are rated for operation between the ambient
temperatures –40°C and 85°C for the E temperature range, and –40°C
to 150°C for the L temperature range. The small geometries of the
BiCMOS process allow these devices to be provided in ultrasmall
packages. The package styles available provide magnetically
