Notes :

*1 Absolute maximum ratings are the limits over which the device may be damaged.

*2 Operating ratings are the conditions for device functioning, but they do not guarantee s

specific performance limit. Refer to the electrical characteristics section for guaranteed

specifications and measuring conditions. Guaranteed specifications apply only to the listed

conditions. If the device does not operate within the listed measuring conditions, there may be

deterioration depending on the performance characteristics.

*3 VCC supply pins 6, 9 and 22 must be connected as one externally in order to prevent internal

damage during the VCC power supply on/switching cycle.

*4 Human model. Discharge via 1.5kΩ from 100pF capacitor.

*5 The typical specified value is +25°C, indicating the standard value of the most general

parameter.

*6 The specified supply current is VCC1 and VCC2 0 input current for RL=[symbol]. Please refer to

the measuring circuit. VCC2 supply current also depends on output load. VCC2 load current is

8mA in the measuring circuit for video output of 1V DC.

*7 Output voltage depends on the load resistor. The measuring circuit uses RL=390Ω.

*8 Measure the gain difference between two amps. Vin=400mVP-P.

*9 Measure Av max. attenuation, and measure the quantitative difference between any two amps.

*10 Special test device on GND sealed PCB not requiring a socket.

*11 Adjust input frequency from 10MHz (AV max. reference value) to -3dB corner frequency.

*12 Measure the output level of two non-operational amps relative to the operating amp to check

channel separation.

*13 200nS minimum pulse width is guaranteed to 15kHz horizontal line. This limit is guaranteed

at the design stage. When using a slower line speed, a clamp pulse with longer pulse width

is required.

*14 4V DC level is the AC output signal center voltage for AC testing. For example, when output

is 4VP-P, the signal fluctuates between 2V DC and 6V DC.

*15 trosd=11nS and tfosd=4ns for V1=V2=V4-0V and video input of 0.7V. The video output

waveform is the waveform shown in the timing diagram, inverted. Therefore, Trosd is actually

rise time, and Tfosd is actually fall time in this situation.

*16 Solder for 10S.
