AD8253
DATA ACQUISITION
The AD8253 makes an excellent instrumentation amplifier
for use in data acquisition systems. Its wide bandwidth, low
distortion, low settling time, and low noise enable it to
condition signals in front of a variety of 16-bit ADCs.
Figure 63 shows the AD825x as part of a total data acquisition
system. The quick slew rate of the AD8253 allows it to condition
rapidly changing signals from the multiplexed inputs. An FPGA
controls the AD7612, AD8253, and ADG1209. In addition,
mechanical switches and jumpers allow users to pin strap the
gains when in transparent gain mode.
This system achieved −116 dB of THD at 1 kHz and a signal-to-
noise ratio of 91 dB during testing, as shown in Figure 62.
