2 / 12 page  Data Sheet P11120EJ3V0DS00 2 µµµµPC1658G PIN CONNECTIONS PIN EXPLANATION Pin No. Pin Name Function and Applications Internal Equivalent Circuit 1 GND Ground pin. This pin should be connected to system ground with minimum inductance. Ground pattern on the board should be formed as possible. All the ground pins must be connected together with wide ground pattern to decrease impedance difference. 2 Test Point Test Point pin. The collector current of Q2 and Q3 can be varied by connecting an appropriate external resistance between this pin and GND or by shorting this pin to GND. By increasing the collector current of Q3, the output level improves and the IC can operate as a low- distortion amplifier. 3 Output Signal output pin. This pin must be coupled to signal source with capacitor for DC cut. 4VCC Power supply pin. This pin should be externally equipped with bypass capacitor to minimize its impedance. 5 Test Point By connecting this pin to the power supply through an appropriate external resistance or by shorting this pin directly to the power supply, the gain can be adjustable (when using pin 2, short the pin 5 to the power supply). 6 Input Signal input pin. Through negative feedback from output pin with an external circuit, the IC operates as a wideband amplifier. 7 8 Bypass Emitter bypass pins of Q1. Bypass these pins to GND with a capacitor.
