Small-Signal Transient Response
Reducing the Closed-Loop Bandwidth
Although it is possible to reduce the closed-loop band-
width by using a feedback zero, instability can occur if the
bandwidth is made too low. An alternate technique is to do
differential filtering at the input of the amplifier. This
technique filters the differential input signal, and the
differential noise, but does not filter common-mode noise.
Common-mode noise is rejected by the LT1189’s CMRR.
10MHz Bandwidth Limited Amplifier
Using the Shutdown Feature
The LT1189 has a unique feature that allows the amplifier
to be shutdown for conserving power, or for multiplexing
several amplifiers onto a common cable. The amplifier will
shutdown by taking pin 5 to V
–
. In shutdown, the amplifier
dissipates 15mW while maintaining a true high impedance
output state of about 20k
in parallel with the feedback
resistors. For MUX applications, the amplifiers may be
configured inverting, non-inverting, or differential. When
the output is loaded with as little as 1k
from the amplifier’s
feedback resistors, the amplifier shuts off in 600ns. This
shutoff can be under the control of HC CMOS operating
between 0V and –5V.
