∗ 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 VCC 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°C) A (CG).
