Differential Line Receiver
T he differential receiver circuit of Figure 43 is useful for many
applications from audio to MRI imaging. It allows extraction of
a low level signal in the presence of common-mode noise. As
shown in Figure 44, the AD797 provides this function with only
9 nV/

noise at the output. Figure 45 shows the AD797’s
20-bit T HD performance over the audio band and 16-bit accu-
racy to 250 kHz.

T he ultralow noise and distortion of the AD797 may be com-
bined with the wide bandwidth, slew rate, and load drive of a
current feedback amplifier to yield a very wide dynamic range
general purpose driver. T he circuit of Figure 46 combines the
AD797 with the AD811 in just such an application. Using the

for Differential Line Receiver
component values shown, this circuit is capable of better than
–90 dB T HD with a
±
5 V, 500 kHz output signal. T he circuit is
therefore suitable for driving high resolution A/D converters and
as an output driver in automatic test equipment (AT E) systems.
Using a 100 kHz sine wave, the circuit will drive a 600
load to
a level of 7 V rms with less than –109 dB T HD, and a 10 k
load at less than –117 dB T HD.
