产品信息
产品概述
AD5421 is a complete, loop-powered, 4mA to 20mA digital-to-analogue converter (DAC) designed to meet the needs of smart transmitter manufacturers in the industrial control industry. The DAC provides a high precision, fully integrated, low cost solution. It includes a regulated voltage output that is used to power itself and other devices in the transmitter. This regulator provides a regulated 1.8V to 12V output voltage. It also contains 1.22V and 2.5V references, thus eliminating the need for a discrete regulator and voltage reference. It can be used with standard Highway Addressable Remote Transducer (HART®) FSK protocol communication circuitry without any degradation in specified performance. It is used in applications such as industrial process control, smart transmitters, HART network connectivity.
