The AD8314 provides two voltage outputs. The first, V_UP, increases from close to ground to about 1.2 V as the input signal level increases from 1.25 mV to 224 mV. This output is intended for use in measurement mode. Consult the Applications section for information on this mode. A capacitor can be connected between the V_UP and FLTR pins when it is desirable to increase the time interval over which averaging of the input waveform occurs.
