The Texas Instruments DAC8742HPBSR is a specialized digital-to-analog converter (DAC) functioning as a low-power modem. It is compliant with HART®, FOUNDATION Fieldbus™, and PROFIBUS PA standards, making it suitable for industrial process control and automation applications.
This device features a flexible interface supporting both SPI and UART protocols. It operates within a voltage range of 2.7V to 5.5V and is designed for a wide operating temperature range of -55°C to 125°C. Key features include integrated HART FSK sinusoids, a programmable amplitude for TX signals, and an integrated RX demodulator with a band-pass filter.
The DAC8742HPBSR is housed in a 32-TQFP package with surface mount mounting type. It is designed for reliability with CRC bit error checking and a watchdog timer. The modem is compatible with FOUNDATION Fieldbus H1 Controller and Medium Attachment Unit (MAU) at 31.25 kbit/s and also compatible with PROFIBUS PA.
Its low quiescent current of 180 µA maximum at typical industrial operating temperatures (-40°C to 85°C) contributes to power efficiency in demanding industrial environments.
