POWER INTERFACE Pin VPOS Supply Voltage 2.7 5.5 V Quiescent Current ENBL high 8.5 10.7 mA Over Temperature −30°C ≤ TA ≤ +85°C 12.9 mA Disable Current6 ENBL low 4 10 μA Over Temperature −30°C ≤ TA ≤ +85°C 13 μA 1 Operation down to 0.02 GHz is possible. 2 Mean and standard deviation specifications are available in Table 2 3 See Figure 12 for plot of input impedance vs. frequency. 4 This parameter is guaranteed but not tested in production. Limit is −3 sigma from the mean. 5 Response time in a closed-loop system depends on the filter capacitor (CFLT) used and the response of the variable gain element. 6 This parameter is guaranteed but not tested in production. Maximum specified limit on this parameter is the 6 sigma value.
