SBOS925A December 2020 – January 2021 OPA391
Factory automation systems commonly use the 4-mA to 20-mA (4-20 mA) communication protocol to enable process automation. In typical 2-wire, 4-mA to 20-mA loop applications, power to the remote transmitter is limited to less than 4 mA total consumption. As a result of the power limitations, low power consumption is essential. The OPA391 solves many design challenges in 4-mA to 20-mA loop applications, where low power, high accuracy, and high bandwidth are required.
|Total current consumption||< 100 μA|
|DAC control voltage||0 V to 4.096 V|
|Output current||4 mA to 20 mA|
