Module description

 

 

The AD8362 is a true root-mean-square response power detector with a measuring

 

range of 65dB, which is mainly used in various high-frequency communication

 

systems and instruments requiring accurate response to signal power. The

 

fluctuating output can be filtered and compared to the output of an identical square

 

whose input is a fixed DC voltage applied to the VTGT pin, usually a precise

 

reference voltage of 1.25V provided on the VREF pin.

 

When used as a power measurement device, the VOUT is bonded to the VSET. In

 

this way, the output is proportional to the logarithm of the root-mean-square value

 

of the input. In other words, the readings will be displayed directly in dB and can be

 

easily adjusted at a ratio of 1V or 50mV/dB per 10x. Other slopes are also easy to

 

achieve. When logical high voltage is applied to the PWDN pin, the AD8362 enters

 

power saving mode with a power consumption of 1.3mW. At 25° C, it can be

 

powered up to a nominal operating current of 20mA in about 20us
