Application examples
BA7207AS (SDIP32)
To cancel the temperature characteristic of the ID, the resistors marked with asterisks should be of the metal film, and have a
temperature coefficient
±
100ppm /
°
C.
: Test pin. Connect to V

if unused.
The 100pF capacitor connected to pin 16 is intended to reduce temperature disper of the gate phase.It should have a static
capacitance tolerance of
±
10% or Ic and a temperature coefficient of
±
30ppm /
°
C ( – 55
°
C to + 125
