AD5700-1ACPZ-RL7 - Brand New Analog Devices Modems - ICs and Modules
-
Description
The AD5700-1ACPZ-RL7 is a single-chip solution designed as a HART® FSK half-duplex modem. It complies with the HART physical layer requirements and integrates all necessary functions, such as filtering, signal detection, modulating, demodulating, and signal generation. This eliminates the need for many external components. With a 0.5% precision internal oscillator, the AD5700-1ACPZ-RL7 greatly reduces board space requirements and is suitable for both master and slave configurations in line-powered applications. It consumes a maximum supply current of 115µA, making it an optimal choice for low-power loop-powered applications. The transmit waveforms are phase continuous 1200 Hz and 2200 Hz sinusoids. The AD5700-1ACPZ-RL7 also features accurate carrier detect circuitry and a standard UART interface.
