MEASUREMENT CIRCUITS
I
Note: Bypass capacitors specified in each measurement circuit below should be connected between VCC
and GND, and VCC2 and GND. Load resistance specified in each measurement circuit below should
be connected to OUT and OUTN pins (excluding measurement circuit 3).
Circuit wiring of bypass capacitors and load resistance should be connected as short as possible. If the
circuit wiring is long, the required characteristics may not be realized. Also, if the values of bypass
capacitors and load resistance differ from the description in this document or are not connected, the
required characteristics may not be realized.
