Initialization time

The OA1MPA, OA2MPA, and OA4MPA series of devices use a proprietary trimming

achieved. The initialization time is defined as the delay after power-up which guarantees

measurement results for different supply voltages and for temperatures varying from -40 °C

to 125 °C.

PCB layouts

For correct operation, it is advised to add a 10 nF decoupling capacitors as close as

possible to the power supply pins.
