## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Amplifier output, which is rail-to-rail per the datasheet features list. |
| 2 | GND | power_in | Negative supply voltage (ground) for the device; the MAX4460 output is referenced to this pin. |
| 3 | IN+ | input | Positive differential input; high-impedance input optimized for small-signal differential voltages. |
| 4 | N.C. | unconnected | No connection; not internally connected. |
| 5 | N.C. | unconnected | No connection; not internally connected. |
| 6 | IN- | input | Negative differential input; high-impedance input optimized for small-signal differential voltages. |
| 7 | VDD | power_in | Positive supply voltage; the device operates from a single supply of 2.85V to 5.25V. |
| 8 | FB | input | Feedback input; connect FB to the center tap of a resistive divider from OUT to GND to set the gain. |
