Texas Instruments · Programmable / Variable Gain Amplifiers (PGA/VGA) · SOIC-14
VCA822IDR from Texas Instruments, in a SOIC-14. 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 | +VCC | power_in | Positive supply pin; the datasheet gives an absolute maximum power supply of ±6.5 V and a recommended operating voltage of 7 V to 12 V (10 V nominal). |
| 2 | VG | input | Gain control input; the gain follows the control voltage linearly in V/V as it varies from +1 V to −1 V, giving a gain of 10 V/V at +1 V and 0.1 V/V at −1 V for a +10 V/V maximum gain. |
| 3 | +VIN | input | Noninverting signal input of the differential-input, single-ended-output variable gain amplifier. |
| 4 | +RG | input | Gain-set resistor connection; the maximum gain equals 2 × (RF / RG), and the maximum gain is intended to be set between +2 V/V and +100 V/V. |
| 5 | -RG | input | Gain-set resistor connection; the maximum gain equals 2 × (RF / RG), and the maximum gain is intended to be set between +2 V/V and +100 V/V. |
| 6 | -VIN | input | Inverting signal input of the differential-input, single-ended-output variable gain amplifier; the input voltage must not exceed ±VS. |
| 7 | -VCC | power_in | Negative supply pin; the datasheet gives an absolute maximum power supply of ±6.5 V and a recommended operating voltage of 7 V to 12 V (10 V nominal). |
| 8 | -VCC | power_in | Negative supply pin; the datasheet gives an absolute maximum power supply of ±6.5 V and a recommended operating voltage of 7 V to 12 V (10 V nominal). |
| 9 | VREF | power_in | Output voltage reference input (listed for the SOIC-14 package only). |
| 10 | VOUT | output | Amplifier output of the feedback amplifier stage, which provides ±160 mA high output current. |
| 11 | GND | power_in | Ground reference pin. |
| 12 | FB | input | Feedback resistor input (RF connection) that sets the maximum gain together with the gain-set resistor RG. |
| 13 | NC | unconnected | No connect pin; leave unconnected. |
| 14 | +VCC | power_in | Positive supply pin; the datasheet gives an absolute maximum power supply of ±6.5 V and a recommended operating voltage of 7 V to 12 V (10 V nominal). |
