Differential Line Receiver
The differential receiver circuit of Figure 47 is useful for many
applications, from audio to MRI imaging. The circuit allows
extraction of a low level signal in the presence of common-
mode noise. As shown in Figure 48, the AD797 provides this
function with only 9 nV/√Hz noise at the output. Figure 49
shows the AD797 20-bit THD performance over the audio band
and the 16-bit accuracy to 250 kHz.

A General-Purpose ATE/Instrumentation I/O Driver
The ultralow noise and distortion of the AD797 can be
combined with the wide bandwidth, slew rate, and load drive
of a current feedback amplifier to yield a very wide dynamic
range general-purpose driver. The circuit shown in Figure 50
combines the AD797 with the AD811 in just such an application.
Using the component values shown, this circuit is capable of
better than 90 dB THD with a ±5 V, 500 kHz output signal.
The circuit is, therefore, suitable for driving a high resolution
ADC as an output driver in automatic test equipment (ATE)
systems. Using a 100 kHz sine wave, the circuit drives a 600 Ω
load to a level of 7 V rms with less than 109 dB THD and a
10 kΩ load at less than 117 dB THD.
