**Analog Devices** · Special Purpose Amplifiers · MSOP-8

AD8310ARMZ 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 | INLO | input | First of two balanced differential inputs, biased roughly to VPOS/2. |
| 2 | COMM | power_in | Common pin, usually grounded, providing internal circuit reference. |
| 3 | OFLT | output | Offset filter access node nominally at 1.75 V that provides dc offset compensation voltage for low-frequency filtering with external capacitor. |
| 4 | VOUT | output | Logarithmic output voltage with maximum 25 mA drive capability and 0.05 Ω output impedance, 24 mV/dB slope. |
| 5 | VPOS | power_in | Positive supply voltage input, 2.7 V to 5.5 V at 8 mA quiescent current. |
| 6 | BFIN | bidirectional | Unbuffered output access point at 6 mV/dB providing signal for external bandwidth filtering via capacitor to ground or feedback slope adjustment via resistor from VOUT. |
| 7 | ENBL | input | CMOS-compatible chip enable input, active high with 2.3 V logic high threshold, consuming 35 μA at 3 V. |
| 8 | INHI | input | Second of two balanced differential inputs, biased roughly to VPOS/2. |
