The SLG7RN47762 HART Modem Modulator/Demodulator IC integrates modulation and demodulation of the HART frequency shift keyed (FSK) signal. The SLG7RN47762V includes a built-in DAC for generating sine waves on a current loop without phase shifts. Also, it contains all the necessary digital blocks for decoding the sine wave back into UART. The compact system-on-chip (SoC) is housed in a 2.0mm x 2.0mm STQFN package.
