Three Realization Methods of Domestic Chip HT1200M Clock

As we all know that HART communication chip A5191HRT needs 460.8KHz passive crystal to run, as the perfect compatible chip of A5191HRT, HT1200M also needs 460.8KHz passive crystal for the chip to use. HT1200M chip development using the clock usually have three methods, respectively, the use of exter

Performance Features and Design of HT1200M

The HART (Highway Addressable Remote Transducer) protocol was launched by Rosemount Company in the United States in the mid-1980s. It is mainly used for digital communication between on-site intelligent instruments and control systems. The HART protocol superimposes audio digital signals on 4~20 mA

NE89 Temperature Transmitter with Digital Signal Processing (Part 3)

1. Analog Output SignalThe measurement signal is mapped to a 4 to 20 mA linear current output signal within the set range.●Output Signal Refresh RateFor normal temperature measurement applications, a rate at which the output signal is refreshed at least once in 1 second is sufficient; for tim
