Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | −FB | output | Negative Output for Feedback Component Connection. |
| 2 | +IN | input | Positive Input Summing Node. |
| 3 | −IN | input | Negative Input Summing Node. |
| 4 | +FB | output | Positive Output for Feedback Component Connection. |
| 5 | MODE | input | Selects between full power mode (4 mA, 145 MHz) when connected to +VS and low power mode (1.4 mA, 80 MHz) when connected to −VS. |
| 6 | +VS | power_in | Positive Supply Voltage with operating range 3 V to 10 V. |
| 7 | +VS | power_in | Positive Supply Voltage with operating range 3 V to 10 V. |
| 8 | +VCLAMP | input | Positive Clamp Level for differential output protection; typically connected to positive ADC reference voltage. |
| 9 | VOCM | input | Output Common-Mode Voltage control pin with 125 kΩ input impedance and voltage range −VS + 0.4 V to +VS − 1.4 V. |
| 10 | +OUT | output | Positive Output for Load Connection with voltage swing of −VS + 0.1 V to +VS − 0.1 V at 1 kΩ load. |
| 11 | −OUT | output | Negative Output for Load Connection with voltage swing of −VS + 0.1 V to +VS − 0.1 V at 1 kΩ load. |
| 12 | DISABLE | input | Disable Pin for power control; active-low with thresholds at −VS − 0.3 V to DGND + 1 V (disabled) and DGND + 1.4 V to +VS + 0.3 V (enabled). |
| 13 | −VCLAMP | input | Negative Clamp Level for differential output protection; typically connected to negative ADC reference voltage. |
| 14 | −VS | power_in | Negative Supply Voltage with operating range 3 V to 10 V. |
| 15 | −VS | power_in | Negative Supply Voltage with operating range 3 V to 10 V. |
| 16 | DGND | power_in | Digital Ground Level with voltage range −VS to +VS − 2.5 V. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
