MAX4003EUA+T from Analog Devices Inc Maxim Integrated, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RFIN | input | RF input. AC-coupled internally via an on-chip 5pF capacitor in series with a ~2kΩ resistance (highpass corner ~16MHz). Requires an off-chip 50Ω impedance match. |
| 2 | SHDN | input | Active-low shutdown input. A logic LOW on SHDN shuts down the entire IC (typ. 13µA shutdown current). Logic thresholds: VIH ≥ 1.8V, VIL ≤ 0.8V. |
| 3 | GND | power_in | Ground. Connect to PC board ground plane. |
| 4 | CLPF | passive | Lowpass filter connection. Connect an external capacitor between CLPF and GND to set the control-loop bandwidth (e.g. 150pF → ~8MHz small-signal bandwidth). A series resistor with CLPF may be added to introduce a zero for loop-dynamics compensation. |
| 5 | GND | power_in | Ground. Connect to PC board ground plane. |
| 6 | N.C. | unconnected | No connection. Leave unconnected or tie to GND. (Not bonded on μMAX; the UCSP variant omits this pin entirely.) |
| 7 | OUT | output | Detector output. Buffered log-detector voltage (~0.36V at -45dBm to ~1.45V at 0dBm RFIN into 50Ω; log slope ≈ 25.5mV/dB at 100MHz). Drive directly into a baseband ADC. Held near GND for ~5µs after power-up to avoid glitches. |
| 8 | VCC | power_in | Supply voltage, +2.7V to +5.0V (5.9mA typ at VCC = 3.0V). Bypass with a capacitor placed as close to the pin as possible; do not share ground vias with other branches. |
