AD8421BRMZ-R7 from Analog Devices, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | -IN | input | Negative differential input pin accepting signals from −VS + 2.3 V to +VS − 1.8 V. |
| 2 | RG | passive | Gain-setting resistor connection pin; place external resistor between pins 2 and 3 to set G = 1 + (9.9 kΩ/RG). |
| 3 | RG | passive | Gain-setting resistor connection pin; place external resistor between pins 2 and 3 to set G = 1 + (9.9 kΩ/RG). |
| 4 | +IN | input | Positive differential input pin accepting signals from −VS + 2.3 V to +VS − 1.8 V. |
| 5 | -VS | power_in | Negative power supply pin for ±2.5 V to ±18 V dual supply operation. |
| 6 | REF | input | Reference voltage input pin with 20 kΩ input impedance for output level shifting; voltage range −VS to +VS. |
| 7 | VOUT | output | Analog output pin with swing from −VS + 1.2 V to +VS − 1.6 V at load resistance RL = 2 kΩ. |
| 8 | +VS | power_in | Positive power supply pin for ±2.5 V to ±18 V dual supply operation. |
