POWER SUPPLY BYPASSING
Correct power supply bypassing is very important
for optimizing the performance in high frequency
ranges. Bypass capacitors should be placed as
close as possible to the IC pins to improve high
frequency bypassing. A capacitor greater than
1
μ
F is necessary to minimize the distortion. For a
better quality bypassing a capacitor of 10nF can
be added using the same implementation condi-
tions. Bypass capacitors must be incorporated for
both the negative and the positive supply.

SINGLE POWER SUPPLY
The following figure shows the case of a 5V single
power supply configuration
Figure 64:
Circuit for +5V single supply
The TS616 operates with power supplies from
12V down to 5V. This can be achieved by either a
dual power supplies of ±6V or ±2.5V or a single
power supply of 12V or 5V referenced to the
ground. In the case of asymmetrical supply, a new
biasing is necessary to assume a positive output
dynamic range between 0V and +V
CC
supply rails.
Considering the values of V
OH
and V
OL
, the ampli-
fier will provide an output dynamic from +0.5V to
10.6V on 25
load for a 12V supply and from
0.45V to 3.8V on 10
load for a 5V supply.
The amplifier must be biased with a mid-supply
(nominally +V
CC
/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
limit the current consumption. On the other hand,
the current must be high enough to bias the
non-inverting input of the amplifier. If we consider
