(75 ? + 75 ? ). therefore, the coupling capacitor should be about 1000 f when a low bandwidth for transmission is considered. (see figure 3.) when the amplifier operates using a dual () power supply, t he operating point can be set at gnd level, and therefore, there is no need for a coupling capacitor to prevent dc output. since a coupling capacitor is not needed, there is no sagging of low-frequency characteristics in output stage. (see figure 4.) 2) generation of negative voltage by charge pump circuit as is shown in figure 5, the charge pump consists of a pair of switches (sw1 and sw2) and a pair of capacitors (flying capacitor and load capacitor), generating a negative voltage. when +3 v is applied to this ic, approximately -2.83 v of negative voltage is obtained. 0v vcc nvc c1 c2 vcc c2 nvcc gnd vcc gnd vcc vcc nvc load voltage pins (7 pins) amp (dual power supply) vcc -vcc 75 75 amp (single power supply) vcc 75 75 1/2v cc bias 1000 f fig.3 fig.4 output capacitor is required due to dc voltage at output pin output capacitor is not required since dc voltage is not applied to output pin

(recomme ndations: 3.3 f, b characteristics, 6.3 v or higher) 8. target capacitor it is recommended to use a ceramic capacitor with good temperature characteristics (b). 9. the nvcc (7 pin) terminal generates a voltage that is us ed within the ic, so it should not be connected to a load unless necessary. this capacitor (c7) has a large capacitance value with low negative voltage ripple. 10. capacitors c18 and c2 should be placed as close as possibl e to the ic. if the wire length to the capacitor is too long, it can lead to switching noise. (recommended c18: 1.0 f; c2: 3.3 f, b characteristics, 6.3 v or higher maximum voltage) 11. the hpf consists of input coupling capacitor c3 and 150 k ? of the internal input. be sure to check for video signal sag before determining the c3 value. the cut-off frequency fc can be calculated using the following formula. fc = 1/(2 c3 150 k ? ) (recommendations: 1.0 f, b characteri stics, 6.3 v or higher maximum voltage) 12. the output resistor r5 should be placed close to the ic. 13. improper mounting may damage the ic. 14. a large current transition occurs in the power supply pin when the charge pump circuit is switched. if this affects other ics (via the power supply line), insert a resistor (approximately 10 ? ) in the vcc line to improve the power supply's ripple effects. although inserting a 10 ? resistor lowers the voltage by about 0.2 v, this ic has a wide margin for low-voltage operation, so dynamic range problems or other problems should not occur.
