PIN | TYPE(1) | DESCRIPTION | ||
---|---|---|---|---|
NAME | NO. | |||
D (SOIC) | RGT (VQFN) | |||
AFE_En | 1 | 14 | I | LNA and Log Detector block enable and disable pin. AFE_En = High for AFE enable. Floating this pin keeps both blocks enabled as well. |
AGND | 13 | 10 | P | Analog ground for LNA and Log detector block |
Buffer | 10 | 7 | O | Noninverting buffered output. VBuffer = VLog_Out × 2. |
DGND | 2 | 15 | P | Digital ground for Freq_Out pin |
Freq_Out | 8 | 5 | O | This pin toggles at the same signal frequency applied at the Log_In. |
Freq_Supply | 7 | 4 | P | Power supply for Freq_Out function. Float this pin if the frequency-detection feature is not required. |
Inv_Buffer | 9 | 6 | O | Inverted buffered output. VInv_Buffer = VLog_Out × –2. |
LNA_En | 3 | 16 | I | Low-noise amplifier enable and disable. LNA_En = High for LNA enable. Floating this pin keeps the LNA enabled as well. |
LNA_In | 16 | 13 | I | Low-noise amplifier input |
LNA_Out | 14 | 11 | O | Low-noise amplifier output |
Log_Inm | 11 | 8 | I | Inverting input of Log Detector block. Connect an appropriate capacitor to ground when used in a single-ended input. Refer to Section 7.3.2. |
Log_Inp | 12 | 9 | I | Noninverting input of Log Detector block |
Log_Out | 5 | 2 | O | Unbuffered output of Log Detector block. Connect an appropriate resistor RF (to set the input to output slope) and capacitor CF (to set the response time). |
Offset_Cap | 15 | 12 | I | Connect a recommended capacitor from this pin to ground. This capacitor sets the pole of the internal offset correction loop. Refer to Section 7.3.1 for the recommended capacitor. |
Ref_Res | 6 | 3 | I | Connect a 1% 56kΩ resistor to this pin. Float this pin if the default relaxed slope accuracy is acceptable. |
VCC | 4 | 1 | P | Supply |
Thermal Pad |
— |
Thermal Pad | P | Thermal pad. Electrically isolated from the device. Connect to a heat spreading plane, typically ground. |
