General Description
The DS8500 is a single-chip modem with Highway
Addressable Remote Transducer (HART) capabilities
and satisfies the HART physical layer requirements.
The device integrates the modulation and demodulation
of the 1200Hz/2200Hz FSK signal, has very low power
consumption, and needs only a few external compo-
nents due to the integrated digital signal processing.
The input signal is sampled by an analog-to-digital con-
verter (ADC), followed by a digital filter/demodulator.
This architecture ensures reliable signal detection in
noisy environments. The output digital-to-analog con-
verter (DAC) generates a sine wave and provides a
clean signal with phase-continuous switching between
1200Hz and 2200Hz. Low power is achieved by dis-
abling the receive circuits during transmit and vice
versa. The DS8500 is ideal for low-power process con-
trol transmitters.
