Current Output Option
If a current output is required, connect the current output,
OUT, to the destination load. To maximize precision, provide a
as low as power line, and above. The recommended averaging,
crest factor and LPF capacitor values are 10 μF, 0.1 μF and
3.3 μF. Refer to the Using the Output Buffer section if additional
low-pass filtering is required.

means for external calibration to replace the internal trimmed
resistor, which is bypassed. This configuration is useful for conve-
nient summing of the AD8436 result with another voltage, or
for polarity inversion.

and are similar to those for dual power supply when the device is
ac-coupled. The analog inputs are all biased to half the supply
voltage, but the output remains referred to ground because the
output of the AD8436 is a current source. An additional bypass
connection is required at IGND to suppress ambient noise.

Converting to Average Rectified Value
To configure the AD8436 for rectified average instead of rms
conversion, simply reduce the value of CAVG to 470 pF (see
between capacitor CAVG and Pin CAVG.
