Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | −FB | output | Negative feedback output terminal; connects to negative input summing node through feedback resistor network for gain setting. |
| 2 | +IN | input | Positive input summing node; unity-gain input terminal for differential signal or feedback current input. |
| 3 | −IN | input | Negative input summing node; unity-gain input terminal for differential signal or feedback current input. |
| 4 | +FB | output | Positive feedback output terminal; connects to positive input summing node through feedback resistor network for gain setting. |
| 5 | +VS | power_in | Positive power supply voltage; operational range 3 V to 7 V for LFCSP package. |
| 6 | +VS | power_in | Positive power supply voltage; operational range 3 V to 7 V for LFCSP package. |
| 7 | +VS | power_in | Positive power supply voltage; operational range 3 V to 7 V for LFCSP package. |
| 8 | +VS | power_in | Positive power supply voltage; operational range 3 V to 7 V for LFCSP package. |
| 9 | VOCM | input | Output common-mode voltage control input; sets DC common-mode level of differential outputs; input impedance approximately 250 kΩ. |
| 10 | +OUT | output | Positive output terminal for load connection; differential output swing −VS + 0.07 V to +VS − 0.07 V; output impedance <1 Ω at DC. |
| 11 | −OUT | output | Negative output terminal for load connection; differential output swing −VS + 0.07 V to +VS − 0.07 V; output impedance <1 Ω at DC. |
| 12 | DISABLE | input | Disable control input; disable amplifier at ≤(−VS + 1) V to reduce quiescent current to 13.5 μA; enable at ≥(−VS + 1.8) V. |
| 13 | −VS | power_in | Negative power supply voltage; ground reference or negative supply for amplifier operation. |
| 14 | −VS | power_in | Negative power supply voltage; ground reference or negative supply for amplifier operation. |
| 15 | −VS | power_in | Negative power supply voltage; ground reference or negative supply for amplifier operation. |
| 16 | −VS | power_in | Negative power supply voltage; ground reference or negative supply for amplifier operation. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
