Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | FB- | output | Inverting output feedback connection for setting closed-loop gain and loop compensation in fully differential feedback topology. |
| 2 | IN+ | input | Noninverting (positive) differential amplifier input accepting common-mode voltage from VS− − 0.1 V to VS+ − 1.2 V. |
| 3 | IN- | input | Inverting (negative) differential amplifier input accepting common-mode voltage from VS− − 0.1 V to VS+ − 1.2 V. |
| 4 | FB+ | output | Noninverting output feedback connection for setting closed-loop gain and loop compensation in fully differential feedback topology. |
| 5 | VS+ | power_in | Positive power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−. |
| 6 | VS+ | power_in | Positive power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−. |
| 7 | VS+ | power_in | Positive power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−. |
| 8 | VS+ | power_in | Positive power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−. |
| 9 | VOCM | input | Output common-mode voltage control input setting differential output average voltage from VS− + 0.45 V to VS+ − 1.2 V; defaults to midsupply when floated. |
| 10 | OUT+ | output | Noninverting (positive) differential amplifier output with rail-to-rail swing capability requiring ≈200 mV headroom; continuous output current ±20 mA. |
| 11 | OUT- | output | Inverting (negative) differential amplifier output with rail-to-rail swing capability requiring ≈200 mV headroom; continuous output current ±20 mA. |
| 12 | PD | input | Power-down control input; threshold high >VS+ − 0.5 V enables normal operation, threshold low <VS+ − 1.8 V disables amplifier reducing quiescent current to 3−40 µA. |
| 13 | VS- | power_in | Negative power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−. |
| 14 | VS- | power_in | Negative power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−. |
| 15 | VS- | power_in | Negative power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−. |
| 16 | VS- | power_in | Negative power supply rail for single or dual supply operation; operating range 2.85 V to 12.6 V total supply voltage VS+ − VS−. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
