PGA308AIDGSR from Texas Instruments, in a VSSOP-10-0.5mm. 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 | DOUT/VCLAMP | output | Dual-use pin for VOUT over-voltage clamping (programmable via resistor divider) or digital push-pull output for sensor configuration; ±10 mA output current limit. |
| 2 | 1W | bidirectional | One-Wire UART-compatible serial interface (4.8k-114k baud) for digital calibration and configuration; can connect to VOUT for three-terminal sensor modules. |
| 3 | GND | power_in | Ground reference. |
| 4 | VS | power_in | Positive power supply input; operating voltage range +2.7V to +5.5V. |
| 5 | VIN1 | input | Bridge sensor signal input; linear input range 0.2V to (VS - 1.4V); ±10 mA input current limit. |
| 6 | VIN2 | input | Bridge sensor signal input; linear input range 0.2V to (VS - 1.4V); ±10 mA input current limit. |
| 7 | VSJ | passive | Output amplifier summing junction; use for compensation with large capacitive loads (>200 pF) and external gain setting resistors. |
| 8 | VFB | passive | Output amplifier feedback sense point for control and over-/under-scale limits; voltage range -30V to +30V; ±10 mA current limit. |
| 9 | VOUT | output | Conditioned sensor analog output; output voltage range 0.05V to (VS - 0.05V); ±160 mA output current capability. |
| 10 | VREF | power_in | Reference voltage for coarse offset adjust (±100 mV range), zero DAC, and fault monitor; selectable for over-/under-scale threshold reference. |
