Module power supply voltage ±5V, ±5V--±15V (maximum ±18V)Module power supply current 5mA, 5mA - 15mAInput signal form, single-endedInput voltage range "45dBm - + 30dBm, within 7VRMSThe input frequency range is DC-8MHz, please refer to the test table for different frequency bandsInput impedance 50 ohmThe output voltage range is 0.85V-2.6V, based on the actual measured value, there are differences between different modulesInput signal characteristics, input couplingAvoid the introduction of DC components, which will make the output value of the module inaccurate; protect the module from being damaged by DC impact; butAdding a large capacitor in the low frequency band will make the charging time constant too largeOutput current 2mA (max)The output is a voltage signal, generally without current.Module dynamic range. 60dB,Module weight 15.1gModule protection, reverse connection protection, unlimited current protectionModule weight 15.1gModule specification, 50*45*14mmLength * width * height-PCB sizeModule shielded, no shielding coverModule heating factor, excessive power supply voltage damages the chip or the module is damagedBadModule operating temperature, 0°C--+70°C. Industrial gradeModule featuresModule power supply LED indication, diode anti-reverse connection, The output stage has a low-pass filter of about 100HzScope of applicationPeak voltage detection, data acquisitionSMA signal input, XH2.54 foolproof socket inputModule interface typeOutput, 5. 08-3PIN power socket

Test pictures show:
Frequency 1KHz input 2Vrms voltmeter output: 2.0001Vrms
Frequency 1KHz Input 7Vrms Voltmeter Output: 7.0293Vrms
Test video:
1, enter a fixed RMS, change the broadband frequency, see the AD637 in the band RMS output flatness
2, the input frequency is fixed, change the input RMS, see the flatness of the AD637 input RMS
3, the input frequency is fixed, change the input value of 1mVrms RMS, see AD637 output performance on the resolution
4, AD637 is the exchange of true RMS detector, it is widely used in power exchange, then we for the 50Hz frequency, the following test video, the input signal is 50Hz change the input RMS, see AD637 in the RMS accuracy Performance
