(75 ? + 75 ? ) for the video driver, the capacity of the coupling capacitor must be on the order of 1000 f if you take into account the low band passband. (fig.3) for an amplifier operated from dual power supplies (+ supply), since the operating point can be at gnd level, a coupling capacitor for preventing output of direct current is not needed. moreover, since a coupling capacitor is not needed, in principle, there is no lowering of the low band characteristic at the output stage. (fig.4) 2) occurrence of negative voltage due to charge pump circuit a charge pump, as shown in fig. 5, consis ts of a pair of switches (sw1, sw2) and a pair of capacitors (flying capacitor, anchor capacitor). switching the pair of switches as show n in fig. 5 causes a negative voltage to occur by shifting the charge in the flying capacitor to the anchor capacitor as in a bucket relay. in this ic, by applying a voltage of +3 v, a negative voltage of approximately -2.8 v is obtained. 0v nvc c1 c2 vcc c2 nvcc gnd vcc gnd vcc vcc nvc negative voltage pin (7pin) dual-supply amplifier vcc -vcc 75 75 single-supply amplifier vcc 75 75 1/2 v cc bias 1000 f fig.3 fig.4 output capacitor required since dc voltage is occurring at output pin output capacitor not required since dc voltage does not occur at output pin c_minus downloaded from: http:///

(recommended c4: 3.3 f, b characteristics, 6.3 v or higher maximum voltage) make mount board patterns follow the layout example shown on page 10 as closely as possible. 2. capacitors to use in view of the temperature characteristics, etc., we recommend a ceramic capacitor with b characteristics. 3. the nvcc (c1 pin) terminal generates a voltage that is used within the ic, so it should never be connected to a load unless absolutely necessary. moreover, this capacitor (c2) has a large capacitance value but very little negative voltage ripple. (recommended c2: 1.0 f, b characteristic, 6.3 v or higher maximum voltage) 4. capacitors c1 and c4 should be placed as close as possible to the ic. if the wiring to the capacitor is too long, it can lead to intrusion of switching noise. (recommended c1: 1.0 f, b characteristics, 6.3 v or higher maximum voltage) 5. the hpf consists of input coupling capacitor c3 and 150 k ? of internal input impedance. be sure to check for video signal sa g before determining the c3 value. the cut-off frequency fc can be calculated using the following formula. fc = 1/(2 c3 150k ) (recommended c3: 1.0 f, b characteristic, 6.3 v or higher maximum voltage) 6. the output resistor r2 should be placed close to the ic. 7. if the ic is mounted in the wrong dire ction, there is a risk of damage due to problems such as inverting vcc and gnd. be careful when mounting it. 8. a large current transition occurs in the power supply pin when the charge pump circ uit 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 l owers 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. (see figures 12 to 14.) we are confident in recommending the above application circuit example, but we ask that you carefully check not just the static characteri stics but also transient characteristics of this circuit before using it. a t playback (active mode) recordin g (input mode) BH76706GU only k y _ _ k y _ _ ?? =u =u video monitor circuit curren =u =u =u =u =u =u ?? downloaded from: http:///
