INA332AIDGKT from Texas Instruments, in a MSOP-8. 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 | RG | passive | Gain-set pin: the impedance between RG, REF (pin 5) and VOUT (pin 6) sets the gain as G = 5 + 5(R2/R1), and gain error from external resistors adds directly to the total error. |
| 2 | VIN- | power_in | Inverting signal input, diode-clamped to the supply rails; input signals that swing more than 0.5V beyond the rails should be limited to 10mA or less, and a bias-current return path must be provided. |
| 3 | VIN+ | power_in | Non-inverting signal input, diode-clamped to the supply rails; input signals that swing more than 0.5V beyond the rails should be limited to 10mA or less, and a bias-current return path must be provided. |
| 4 | V- | power_in | Negative power supply terminal; the device is specified for a total supply V+ to V- of +2.7V to +5.5V, and the supply should be decoupled with 0.1µF capacitors close to the device. |
| 5 | REF | input | Reference terminal that defines the zero output voltage level; it requires a low-impedance connection (as little as 160Ω in series degrades CMRR to 50dB) and must be at least 1.2V below the positive supply rail. |
| 6 | VOUT | output | Amplifier output, referred to the REF pin; it swings to within 25mV of the supply rails for gains of 10 or greater with loads above 10kΩ, and short-circuit current is specified as +48/-32 mA. |
| 7 | V+ | power_in | Positive power supply terminal; the device is fully specified from +2.7V to +5.5V with quiescent current of 490µA max per channel and must be at least 1.2V above the REF voltage. |
| 8 | Shutdown | input | Shutdown control, nominally connected to V+; pulling it below 0.8V on a 5V supply puts the amplifier into sleep mode (under 2µA draw), and the threshold varies with supply per the Shutdown Voltage vs Supply Voltage curve. |
