UNITS
Note 2:
Does not include external feedback network resistance.
Note 3:
Applies to all digital input pins (EN, LE, and A0).
Note 4:
Specified with feedback network chosen for optimal AC performance. See Tables 1 and 2 for recommended component
values.
Note 5:
Input test signal: 3.58MHz sine wave of amplitude 40IRE superimposed on a linear ramp (0IRE to 100IRE). IRE is a unit of
video-signal amplitude developed by the International Radio Engineers. 140IRE = 1.0V.
Note 6:
See timing diagram (Figure 5).
Note 7:
Channel-switching time specified for switching between the two input channels; does not include signal rise/fall times for
switching between channels with different input voltages.
Note 8:
Guaranteed by design; not production tested.
Note 9:
Output enable/disable delay times do not include amplifier output slewing times.
Note 10:
Switching transient measured while switching between two grounded channels.
