TSH110-TSH111-TSH112-TSH113-TSH114

The amplifier must be biased with a mid supply
(nominaly +Vcc/2), in order to maintain the DC
component of the signal at this value. Several op-
tions are possible to provide this bias supply (such
as a virtual ground using an operational amplifier),
or a two-resistance divider which is the cheapest
solution. A high resistance value is required to lim-
it the current consumption. On the other hand, the
current must be high enough to bias the non-in-
verting input of the amplifier. If we consider this
bias current (5
μ
A) as the 1% of the current
through the resistance divider (500
μ
A) to keep a
stable mid supply, two 5k
resistances can be
used.
The input provides a high pass filter with a break
frequency below 10Hz which is necessary to re-
move the original 0 volt DC component of the input
signal, and to hold it at 2.5V.
Video Multiplexing using the TSH113
(fig.35):
Circuit for switching 3 video signals with the tri-
ple TSH113.
Assuming a low level active onto the disable pins
(1,2,3) as described on page 7 of the datasheet,
any operator can be disable/enable independent-
ly. The two disabled operators will be in standby
mode featuring a high ouput impedance with a
high input/output isolation and a low quiescent
current.
