CALCULATING SETTLING TIME
Figure used closely approximate time required AD737 settle when input level reduced amplitude. time required converter settle difference between times extracted from graph: initial time minus final settling time. example, consider following conditions: averaging capacitor, initial input level final (reduced) input level From Figure initial settling time (where line intersects line) approximately settling time corresponding final input level approximately seconds. Therefore, time circuit settle value seconds minus which 7.92 seconds. Note that because smooth decay characteristic inherent with capacitor/diode combination, this total settling time final value (not settling time 0.1%, final value). Also, this graph provides worst-case settling time, because AD737 settles very quickly with increasing input levels.

This involves squaring signal, taking average, then obtaining square root. True converters smart rectifiers; they provide accurate reading regardless type waveform being measured. However, average responding converters exhibit very high errors when their input signals deviate from their precalibrated waveform; magnitude error depends type waveform being measured. example, average responding converter calibrated measure value sine wave voltages then used measure either symmetrical square waves voltages, converter computational error reading) higher than true value (see Table

average responding connection, averaging carried post filter consisting internal scale-factor resistor connected between external averaging capacitor, circuit, this additional filtering stage helps reduce output ripple that removed averaging capacitor, CAV. final subsection, bias section, permits power-down function. This reduces idle current AD737 from down mere This feature selected tying terminal.
MEASUREMENT-CHOOSING OPTIMUM VALUE
Because external averaging capacitor, CAV, holds rectified input signal during computation, value directly affects accuracy measurement, especially frequencies. Furthermore, because averaging capacitor appears across diode core, averaging time constant increases exponentially input signal reduced. This means that input level decreases, errors nonideal averaging decrease while time takes circuit settle level increases. Therefore, lower input levels allow circuit perform better (due increased averaging) increase waiting time between measurements. When selecting CAV, trade-off between computational accuracy settling time required.
