Download the DAC8741H datasheet PDF.
This datasheet also covers the DAC8740H variant, as both devices belong to the same low-power modems family and are provided as variant models within a single manufacturer datasheet.
General Description
The DAC8740H and DAC8741H (DAC874xH) are HART®, FOUNDATION Fieldbus™, and PROFIBUS PA compatible low-power modems designed for industrial process control and industrial-automation applications.
Key Features
1 HART-compliant physical layer modem.
1200-Hz, 2200-Hz HART FSK sinusoids.
Register programmable amplitude of TX signals (DAC8741H only).
Integrated RX demodulator and band-pass filter with minimal external components.
