AD8510/AD8512/AD8513
Signal Transmission Applications
One popular signal transmission method uses pulse-width
modulation. High data rates may require a fast comparator
rather than an op amp. However, the need for sharp and
undistorted signals may favor using a linear amplifier.

The AD8510/AD8512/AD8513 make excellent voltage
comparators. In addition to a high slew rate, the AD8510/
AD8512/AD8513 have a very fast saturation recovery time. In
the absence of feedback, the amplifiers are in open-loop mode
(very high gain). In this mode of operation, they spend much of
their time in saturation.
The circuit in Figure 54 compares two signals of different
frequencies, namely a 100 Hz sine wave and a 1 kHz triangular
wave. Figure 56 shows a scope photograph of the output wave-
form. A pull-up resistor (typically 5 k) may be connected from
the output to V
CC
if the output voltage needs to reach the posi-
tive rail. The trade-off is that power consumption will be higher.

Crosstalk
Crosstalk, also known as channel separation, is a measure of
signal feedthrough from one channel to the other on the same
IC. The AD8512/AD8513 have a channel separation better than
90 dB for frequencies up to 10 kHz, and better than 50 dB for
frequencies up to 10 MHz. Figure 57 shows the typical channel
separation behavior between amplifier A (driving amplifier),
with respect to amplifiers B, C, and D.
