AD8218BRMZ-R7
Analog Devices · Current-Sensing Amplifiers · MSOP-8
AD8218BRMZ-R7 from Analog Devices, 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 | +IN | input | Noninverting input of the shunt amplifier, which also powers the internal LDO from 4 V to 80 V when VS is floating. |
| 2 | VS | power_in | Supply pin, bypass with a standard 0.1 µF capacitor; may be left floating or driven from a low impedance 4 V to 5.5 V supply. |
| 3 | ENB | input | Enable pin; connect to GND to enable the internal 80 mV reference. |
| 4 | GND | power_in | Ground. |
| 5 | OUT | output | Buffered output with gain of 20 V/V, internally clamped to 5.2 V. |
| 6 | NC | unconnected | No connect; do not connect to this pin. |
| 7 | REF | input | Reference input with 1 V/V gain to the output (0 V to 5 V range); connect to a low impedance voltage. |
| 8 | −IN | input | Inverting input of the shunt amplifier. |
