AD5700BCPZ-RL7

Overview

The AD5700BCPZ-RL7 is a low-power HART FSK half-duplex modem manufactured by Analog Devices. It integrates modulation, demodulation, and filtering functions for industrial communication. The device operates on a 1.71 V to 5.5 V supply with a maximum receive current of 115 µA. It supports UART interfaces and utilizes 1200 Hz and 2200 Hz shift frequencies. The component is housed in a 4 mm × 4 mm LFCSP-24 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Fully integrated HART-compliant FSK modem with minimal external component requirements
• Ultralow power consumption suitable for intrinsically safe and loop-powered applications
• Integrated buffered HART output providing extra drive capability
• 8 kV HBM ESD rating for robust operation in harsh environments

Applications

• Field transmitters
• HART multiplexers
• PLC and DCS analog I/O modules
• HART network connectivity

Procurement Notes

Verify the specific suffix RL7 against official documentation to confirm reel packaging specifications. Ensure compatibility with system voltage levels between 1.71 V and 5.5 V. Confirm thermal management requirements for the LFCSP-24 package under maximum operating temperatures up to +125°C. Cross-reference pin configurations with the latest datasheet revision G to avoid interface mismatches.

Selection Notes

Select this component for applications requiring certified HART physical layer compliance. Consider the AD5700-1 variant if an internal precision oscillator is needed to reduce board space. Evaluate power constraints against the 115 µA receive mode specification. Ensure the design accommodates the required crystal or clock source configuration for the chosen clocking scheme.
