SGM620XS8G from SGMICRO, in a SOIC-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 | RG | passive | Gain setting pin. Connect an external gain resistor between pin 1 and pin 8 to set gain: G = 1 + (49.4kΩ/RG). Gain range 1 to 10000. |
| 2 | IN- | input | Inverting input pin of the instrumentation amplifier. Input impedance 10GΩ |
| 3 | IN+ | input | Non-inverting input pin of the instrumentation amplifier. Input impedance 10GΩ |
| 4 | -VS | power_in | Negative power supply pin. Operating range -2.3V to -18V for dual supply, or GND for single-supply operation up to 36V total across +VS to -VS. |
| 5 | REF | input | Voltage reference pin used to shift the output level. Must be driven from a low-impedance source (reference input resistance ~18kΩ, reference input current ~30µA typ). |
| 6 | OUT | output | Rail-to-rail output pin. Drives load (RL = 2kΩ nominal). Short-circuit current typically 24mA. Output swing within ~310mV/150mV of the supply rails at ±18V. |
| 7 | +VS | power_in | Positive power supply pin. Operating range +2.3V to +18V for dual supply, or 4.6V to 36V for single-supply operation. |
| 8 | RG | passive | Gain setting pin. Connect an external gain resistor between pin 1 and pin 8 to set gain: G = 1 + (49.4kΩ/RG). Gain range 1 to 10000. |
