1 CFLT Connection for an External Capacitor, CFLT, to Reduce the Modulation Content from the Output Voltage. It also slows the response of the output and reduces the noise seen on the output. The capacitor is connected between CFLT and VLOG. See the Filter Capacitor section for choosing the correct CFLT value. 2 VPOS Positive Supply. The positive supply voltage (VPOS) range is from 2.5 V to 5.5 V. Use decoupling capacitors near this pin on the printed circuit board. 3 RFIN RF Input. 5 pF ac coupling capacitor on chip. Connect a 52.3 Ω shunt resistor near this pin for broadband 50 Ω match. See the Input Coupling Options section for more matching options. 4 COMM Device Common (Ground). Connect this pin to system ground using a low impedance path. 5 VLOG Logarithmic Output. The output voltage (VLog) increases with increasing input amplitude. The output is proportional to the logarithm of the input signal level. 6 ENBL Device Enable. Connect the ENBL pin to a logic high (1.2 V to VPOS) to enable the device. Connect the ENBL pin to a logic low (0 V to 0.5 V) to disable the device. Rev.
