Notes 1. Do not leave the Internally Connected (IC) pin open because it is a base-open pin. Connect this pin to VCC
or GND.
2. Am: Amplitude modulation (Carrier frequency is 31.5 kHz (2fH))
Remark Use the following for external parts.
Resistor (∗) : Metal film resistor (±1%). Unless otherwise specified; ±5%
Capacitors (∗∗) : Tantalum capacitor (±10%). Unless otherwise specified; ±20%
Variable resistors: ±10%
