Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTPUT 1 | output | Op Amp 1 (voltage-control) output; output voltage swing is 27 V min high and 100 mV max low at VCC=30V, RL=10kΩ. |
| 2 | INPUT 1- | input | Op Amp 1 inverting input; input bias current is 20 nA typ and 150 nA max at TA=+25°C, and input voltages must stay within -0.3 V to VCC+0.3 V. |
| 3 | INPUT 1+/VKA | input | Op Amp 1 non-inverting input, internally tied to the 2.5 V shunt reference output (cathode VKA); reference cathode current IK is limited to 100 mA max. |
| 4 | GND | power_in | Ground reference for the device; VCC is specified as VCC to GND, with 40 V absolute maximum supply voltage. |
| 5 | INPUT 2+ | input | Op Amp 2 (current-control) non-inverting input; input voltage range is 0 to VCC-1.5 V at VCC = 0 to 36 V. |
| 6 | INPUT 2- | input | Op Amp 2 inverting input; input differential voltage (VID, pins 5 and 6) is rated 40 V max. |
| 7 | OUTPUT 2 | output | Op Amp 2 output; output current is 20 mA min source and 8 mA min sink at VCC=15V, VO=2V. |
| 8 | VCC | power_in | Positive power supply; recommended range is 3 V to 36 V, with 40 V absolute maximum. |
