The AD8314 provides two voltage outputs. The first, called 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 of this data sheet for information on use in this mode. A capacitor may 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.
