| | | | AM422-2 - Voltage-to-Current Converter IC (Current-Loop Appl.) | | | Overview | Details | Accessories | Documents | Inquiry / Samples |  | AM422-2 is a voltage-to-current converter IC with integrated protection functions especially suitable for industrial sensing and signal-conditioning in current-loop applications. It converts a single-ended input voltage into a current output signal (e.g. 4 .. 20 mA) with adjustable offset and full-scale current. | Applications | - Sensor signal-conditioner
- Current-loop transmitter
| - Protected V/I-converter IC
- Analog back end for µC
| - Voltage driven current source
- Industrial process control
