General Description
The DS8500 is a single-chip modem with Highway
Addressable Remote Transducer (HART) capabilities. It
has been fully tested and verified and has received a
HART® Certificate of Registration. The device integrates
the modulation and demodulation of the 1200Hz/2200Hz
FSK signal, has very low power consumption, and
needs only a few external components due to the integrated digital signal processing. The input signal is
sampled by an analog-to-digital converter (ADC), followed by a digital filter/demodulator. This architecture
ensures reliable signal detection in noisy environments.
The output digital-to-analog converter (DAC) generates
a sine wave and provides a clean signal with phasecontinuous switching between 1200Hz and 2200Hz.
Low power is achieved by disabling the receive circuits
during transmit and vice versa. The DS8500 is ideal for
low-power process control transmitters
