VCA820IDGSR from Texas Instruments, 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 | I- | input | Feedback resistor input; the maximum gain is set externally by the feedback resistor Rf and gain-set resistor Rg, with maximum gain equal to 2 x (Rf/Rg). |
| 2 | +V | power_in | Positive supply pin; the absolute maximum power supply is ±6.3 V and the recommended operating voltage is 7 V to 12 V. |
| 3 | VG | input | Gain control input; gain decreases linearly in dB as VG falls from +2 V to 0 V, giving over 40 dB of gain adjust range. |
| 4 | +VIN | input | Noninverting input of the differential-to-single-ended input stage; input voltage must not exceed ±VS per the absolute maximum ratings. |
| 5 | +RG | input | Gain-set resistor connection; together with -RG and the feedback resistor it sets the maximum gain, which is intended to be between +2 V/V and +100 V/V. |
| 6 | -RG | input | Gain-set resistor connection; together with +RG and the feedback resistor it sets the maximum gain, which is intended to be between +2 V/V and +100 V/V. |
| 7 | -VIN | input | Inverting input of the differential-to-single-ended input stage; input voltage must not exceed ±VS per the absolute maximum ratings. |
| 8 | -V | power_in | Negative supply pin; the absolute maximum power supply is ±6.3 V and the recommended operating voltage is 7 V to 12 V. |
| 9 | VOUT | output | Single-ended output of the amplifier, which provides high output current of 160 mA. |
| 10 | GND | power_in | Ground reference pin for the device. |
