VCA820IDGSR

Texas Instruments · Programmable / Variable Gain Amplifiers (PGA/VGA) · MSOP-10

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.
