INA170EA from Texas Instruments, in a VSSOP-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 | VIN- | power_in | Inverting differential sense input; accurate measurement is specified up to a 0.5V differential input, and a more-negative voltage here reduces the output current toward zero. |
| 2 | VIN+ | power_in | Noninverting differential sense input, connected as close as possible to the shunt; common-mode range is +2.7V to +60V, and a differential input up to 2V will not cause damage. |
| 3 | VREF | power_in | Reference voltage input that, when a positive voltage is applied, drives current through ROS to offset the output current from zero (VOS = (RL/ROS) × VREF). |
| 4 | GND | power_in | Ground reference for the device and for the load resistor RL at pin 6. |
| 5 | ROS | passive | Offset programming resistor connection; programming current through ROS is specified from 0 to 1 mA. |
| 6 | OUT | output | Output current terminal converted to voltage by external load resistor RL; maximum output is limited to (V+) − 0.7V − (VIN+ − VIN−) or VIN− − 0.5V, whichever is lower. |
| 7 | NC | unconnected | No internal connection; leave unconnected. |
| 8 | V+ | power_in | Supply voltage pin with an operating range of +2.7V to +40V (absolute maximum 40V to GND). |
