AD5700-1ACPZ-RL7

AD5700-1 is a single-chip solution, designed and specified to operate as a HART® FSK half-duplex modem, complying with the HART physical layer requirement. This device integrate all of the necessary filtering, signal detection, modulating, demodulating and signal generation functions, thus requiring few external components. The 0.5% precision internal oscillator on the device greatly reduces the board space requirements, making it ideal for line-powered applications. It is widely used in application such as field transmitters, HART multiplexers, PLC and DCS analogue I/O modules, HART network connectivity etc.
