AD8531ARZ from UMW, in a SOP-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 | NC | unconnected | No connect. Leave floating or tie to any convenient potential; not internally bonded. |
| 2 | -INA | input | Inverting input of amplifier A. Rail-to-rail input; common-mode range 0 V to Vs. Input bias current typ 5 pA. |
| 3 | +INA | input | Non-inverting input of amplifier A. Rail-to-rail input; common-mode range 0 V to Vs. Input bias current typ 5 pA. |
| 4 | V- | power_in | Negative supply rail (ground in single-supply operation). Total supply voltage V+ − V- must be between 2.7 V and 6 V (7 V absolute max). |
| 5 | NC | unconnected | No connect. Leave floating or tie to any convenient potential; not internally bonded. |
| 6 | OUTA | output | Amplifier A output. Rail-to-rail output capable of sourcing/sinking ±250 mA. Closed-loop output impedance 40-60 Ω at 1 MHz (Av=1). |
| 7 | V+ | power_in | Positive supply rail. Single-supply operation from 2.7 V to 6 V (7 V absolute max). Supply current typ 0.75 mA at 5 V. |
| 8 | NC | unconnected | No connect. Leave floating or tie to any convenient potential; not internally bonded. |
