SSM2167-1RMZ-R7 from Analog Devices, in a MSOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference for the device, to be connected to the system analog ground in a single-point (star) ground layout. |
| 2 | VCAIN | input | Input to the VCA, which must be AC-coupled from BUFOUT (pin 4) through a blocking capacitor C2, typically 4.7 µF to 10 µF, because the 1 kΩ input impedance sets the lower −3 dB cutoff. |
| 3 | SHUTDOWN | input | Active-low, CMOS-compatible power-down input; applying 0 V reduces supply current to under 10 µA and places the input and output circuitry in a high-impedance state. |
| 4 | BUFOUT | output | Output of the unity-gain input buffer, which drives the VCA input (VCAIN, pin 2) through an external blocking capacitor. |
| 5 | INPUT | input | Microphone signal input to the input buffer, presenting approximately 100 kΩ to the source and carrying an internal DC bias of about 400 mV, so a blocking capacitor (0.1 µF is a good choice) is required for ground-referenced sources. |
| 6 | AVG CAP | passive | Connection for the external level-detector averaging capacitor CAVG, which should be 2.2 µF for low-frequency operation to 10 Hz and electrolytic in the range of 2 µF to 22 µF. |
| 7 | GATE THRS | passive | Connection for the noise-gate threshold resistor RGATE, which is connected to VDD and sets the downward expansion threshold from −40 dBV (0 Ω) to −55 dBV (5 kΩ); values above 5 kΩ are not recommended. |
| 8 | COMPRESSION RATIO | passive | Connection for the compression-ratio resistor RCOMP, which is connected to VDD and sets the ratio from 1:1 (0 Ω short) to 10:1 (175 kΩ); resistor values should be greater than 5 kΩ because lower values may be interpreted as a short. |
| 9 | OUTPUT | output | VCA output with a typical output impedance below 145 Ω, which requires an external load greater than 5 kΩ and a blocking capacitor for grounded loads because the nominal DC output is about 1.4 V. |
| 10 | VDD | power_in | Positive supply pin, specified for 2.5 V to 5.5 V operation with an absolute maximum supply rating of 6 V. |
