I have packed it in Tube. There is a package called 16-WFDFN Exposed Pad. Using it as a Single Phase meter is possible. There is an option in Surface Mount. Temperature at -40°C~125°C is extended during operation. The unit is powered by a 2.7V~100V power supply. If you are looking for parts similar to this one, search LTC2946. The part has 16 terminations. Analog POWER SUPPLY SUPPORT CIRCUIT PMIC IC with powerful performance. It is normal for the part to require 48V volts. This device may not be able to operate without a voltage of 4V or higher. In order to keep the voltage at a reasonable level, the device's maximum voltage should not exceed 100V. 16 pins are attached to it. As far as the device is concerned, it is a 900μA device. Inside this logic device, there are 3 channels.
