Video signal switcher for AV amplifiers
BA7626 / BA7626F
The BA7626 and BA7626F are video signal switches that contain two five-channel analog multiplexers for switching chroma and audio signals, and two wide-band 6dB amplifiers. By simply adding transistor buffers to the outputs, it is possible to construct a record / playback switch for two record / playback VCRs, and three video playback machines (eg. laser desk players). Input switching and VCR record switching can be done independently. The inputs are termi­nated with 20kΩ resistors, and are suitable for switching chroma and audio signals.
•
Applications
AV amplifiers (audio signals and S-pin chroma signals) and video selectors
•
Features
1) 5-input / 3-output switches.
2) 20kΩ input impedance.
3) Built-in 6dB amplifiers.
4) 5V supply voltage.

Note 6
Note 1: Connect a distortion meter to the output, and input a f = 1kHz sine wave. Adjust the input level until the output distortion is 0.5%.
This output voltage at this time is the maximum output level V
om
(V
P-P
).
Note 2: Input a 1V

Note 3: Input a 1V
P-P
, 4.43MHz sine wave. The interchannel crosstalk (in dB) is given by CT = 20 log (V

Note 4: Input 1V
P-P
, 1MHz and 10MHz sine waves. The frequency characteristic (in dB) is given by Gf = 20 log (V

(f = 10MHz) / V
OUT
(f = 1MHz)).
Note 5: Input a 1V
P-P
, 4.43MHz sine wave. The mute level is given by CTM = 20 log (V
OUT

Note 6: Input a 1V
