FUNCTIONALITY AND SETTING
THRESHOLD LEVELS WITH THE
REFERENCE PIN
The THS3095 features a power-down pin (PD) which
lowers the quiescent current from 9.5 mA down to
500
A, ideal for reducing system power.
The power-down pin of the amplifier defaults to the
positive supply voltage in the absence of an applied
voltage, putting the amplifier in the power-on mode of
operation. To turn off the amplifier in an effort to
conserve power, the power-down pin can be driven
towards the negative rail. The threshold voltages for
power-on and power-down are relative to the supply
rails and are given in the specification tables. Above
the Enable Threshold Voltage, the device is on.

Below the Disable Threshold Voltage, the device is
off. Behavior in between these threshold voltages is

the amplifier consumes less power in power-down
mode. The power-down mode is not intended to
provide a high-impedance output. In other words, the
power-down functionality is not intended to allow use
as a 3-state bus driver. When in power-down mode,
the impedance looking back into the output of the
amplifier
is
dominated
by
the
feedback
and
gain-setting resistors, but the output impedance of the
device itself varies depending on the voltage applied
to the outputs.
Figure 70 shows the total system output impedance
which includes the amplifier output impedance in
parallel with the feedback plus gain resistors, which
cumulate to 2380
. Figure 59 shows this circuit
configuration for reference.
