5.9 Typical Characteristics: VCC = 3.3V

at TA = 25°C, VCC = 3.3V, CF = 1nF, RF = 30kΩ (slope = 30mV/dB) and Ref_Res = 1% 56kΩ, and 10nF capacitor to AGND on Log_Inp and Log_Inm, (unless otherwise noted). For AFE, 2nd-order BPF centered around frequency "f" with gain = -7dB used between LNA and Log Detector block.
