Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | M2 | input | Mode Input pin; selects output mode configuration; internally pulled low with 1μA |
| 2 | M1 | input | Mode Input pin; selects voltage or current output mode; internally pulled low with 1μA |
| 3 | VIN | power_in | Noninverting Signal Input for operational amplifier; voltage range (V−)+3V to (V+)−3V |
| 4 | SET | input | Input for Gain Setting and Inverting Input for operational amplifier; voltage range (V−)+3V to (V+)−3V |
| 5 | IMON | output | Current Monitor Output; provides 1/10 copy of output current; output swing (V−)+3V to (V+)−3V |
| 6 | IAOUT | output | Instrumentation Amplifier Signal Output current; output swing (V−)+3V to (V+)−3V |
| 7 | IAIN− | input | Instrumentation Amplifier Inverting Input; voltage range (V−)+3V to (V+)−3V |
| 8 | IAIN+ | input | Instrumentation Amplifier Noninverting Input; voltage range (V−)+3V to (V+)−3V |
| 9 | RG1 | passive | Instrumentation Amplifier Gain Resistor connection point; external resistor determines IA gain per IAOUT=2(IAIN+−IAIN−)/RGAIN |
| 10 | RG2 | passive | Instrumentation Amplifier Gain Resistor connection point; external resistor determines IA gain per IAOUT=2(IAIN+−IAIN−)/RGAIN |
| 11 | V− | power_in | Negative Power Supply; operating voltage range ±5V to ±22V; must connect exposed thermal pad to this pin |
| 12 | NC | unconnected | No Internal Connection |
| 13 | DRV | output | Operational Amplifier Output; voltage swing (V−)+3V to (V+)−3V; short-circuit current ±15mA to ±24mA depending on mode |
| 14 | NC | unconnected | No Internal Connection |
| 15 | V+ | power_in | Positive Power Supply; operating voltage range ±5V to ±22V; absolute maximum +44V |
| 16 | DGND | power_in | Ground for Digital I/O; must be within (V−) ≤ DGND ≤ (V+)−7V; carries digital output sink current |
| 17 | EFCM | output | Error Flag for Common-Mode Over-Range, Active Low; open-drain output with internal 1μA pull-up; indicates IA input exceeds linear range |
| 18 | EFLD | output | Error Flag for Load Error, Active Low; open-drain output with internal 1μA pull-up; indicates short-circuit or open-load condition |
| 19 | EFOT | output | Error Flag for Over-Temperature, Active Low; open-drain output with internal 1μA pull-up; activates at +140°C, resets at +125°C |
| 20 | OD | input | Output Disable, Disabled Low; digital input disables DRV output when driven low; internally pulled high with 1μA |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
