AD8418AWBRZ-RL from Analog Devices, in a SOIC-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 | −IN | input | Negative input of the differential current-shunt amplifier; input common-mode range is −2 V to +70 V continuous operation. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | VREF2 | input | Reference input 2, whose operating range is from GND to VS; it has no operational difference from VREF1 and sets the output offset through internal resistors. |
| 4 | NC | unconnected | No connect; do not connect to this pin. |
| 5 | OUT | output | Buffered output; with RL = 25 kΩ the output voltage range is 0.032 V to VS − 0.032 V. |
| 6 | VS | power_in | Supply pin; operating range is 2.7 V to 5.5 V, with an absolute maximum supply voltage of 6 V. |
| 7 | VREF1 | input | Reference input 1, whose operating range is from GND to VS; it has no operational difference from VREF2 and sets the output offset through internal resistors. |
| 8 | +IN | input | Positive input of the differential current-shunt amplifier; input common-mode range is −2 V to +70 V continuous operation. |
