05260-002 Figure 2. Pin Configuration
Table 3. Pin Function Descriptions Ball No. Mnemonic Description
1 VPOS Positive Supply Voltage (VS), 2.7 V to 5.5 V. 2 VOUT Logarithmic Output. Output voltage increases with increasing input amplitude. 3 VSET Setpoint Input. Connect VSET to VOUT for measurement mode operation. The nominal logarithmic slope of 20 mV/dB can be increased to an arbitrarily high value by attenuating the signal between VOUT and VSET (see the Increasing the Logarithmic Slope section). 4 CFLT Connection for an External Capacitor to Slow the Response of the Output. Capacitor is connected between CFLT and VOUT. 5 COMM Device Common (Ground). 6 RFIN RF Input. Rev.
