AD5700-1BCPZ-RL7

Overview

The AD5700-1BCPZ-RL7 is a low-power HART FSK half-duplex modem manufactured by Analog Devices. It integrates modulation, demodulation, filtering, and signal generation functions compliant with the HART physical layer. The device features a precision internal oscillator, eliminating the need for external crystals. It operates on a supply voltage of 1.71 V to 5.5 V with a maximum receive mode current of 115 µA. Key specifications include 1200 Hz and 2200 Hz shift frequencies, an 8 kV HBM ESD rating, and operation from -40°C to +125°C. It utilizes a UART interface and is housed in a 4 mm × 4 mm LFCSP package.

Feature Summary

• Fully integrated HART-compliant FSK modem with minimal external component requirements
• Precision internal RC oscillator eliminates the need for external crystals
• Buffered HART output provides extra drive capability without external buffering
• Integrated receive band-pass filter with selectable configuration options

Applications

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

Procurement Notes

Verify the specific suffix RL7 corresponds to the reel packaging format required for your assembly line. Confirm that the B grade meets your temperature and performance specifications within the industrial range. Ensure compatibility with the system's UART logic levels and power supply constraints before finalizing the order.

Selection Notes

Select the AD5700-1 variant specifically when board space optimization is critical due to its integrated precision internal oscillator. This model removes the requirement for external crystal components compared to the standard AD5700. Verify that the 1.71 V minimum supply voltage aligns with the loop-powered or line-powered application design constraints.

Part Context

This component belongs to the AD5700/AD5700-1 series of low-power HART modems. The AD5700-1 distinguishes itself by including a precision internal oscillator, whereas the base AD5700 requires an external clock source. Both models share identical integration levels for modulation, demodulation, and filtering functions designed for industrial communication protocols.
