Figure 37. Settling Time Test Circuit
DIFFERENTIAL LINE RECEIVER
The differential receiver circuit of Figure 39 is useful for many
applications from audio to video. It allows extraction of a low
level signal in the presence of common-mode noise. As shown
in Figure 40, the AD818 provides this function with only
10 nV/
√
Hz
noise at the output.

AD818 SETTLING TIME
Settling time is comprised primarily of two regions. The first is
the slew time in which the amplifier is overdriven, where the
output voltage rate of change is at its maximum. The second is
the linear time period required for the amplifier to settle to
within a specified percent of the final value.
Measuring the rapid settling time of AD818 (45 ns to 0.1% and
80 ns to 0.01%—10 V step) requires applying an input pulse
with a very fast edge and an extremely flat top. With the AD818
configured in a gain of –1, a clamped false summing junction
responds when the output error is within the sum of two diode
voltages (approximately 1 volt). The signal is then amplified 20
times by a clamped amplifier whose output is connected directly
to a sampling oscilloscope.
A High Performance Video Line Driver
The buffer circuit shown in Figure 38 will drive a back-termi-
nated 75
video line to standard video levels (1 V p-p) with
0.1 dB gain flatness to 55 MHz with only 0.05
°
and 0.01%
differential phase and gain at the 3.58 MHz NTSC subcarrier
frequency. This level of performance, which meets the require-
ments for high-definition video displays and test equipment, is
achieved using only 7 mA quiescent current.
