Typical Applications
AD5700-1BCPZ-RL is suitable for 6 applications: Industrial Process Control, Smart Transmitters, Valve Positioners, Field Instruments, Process Automation, Remote Monitoring.
Industrial Process Control
The AD5700-1BCPZ-RL is ideal for industrial process control systems that require HART communication over 4-20 mA loops. Its low power consumption (86 µA in listen mode) and wide supply voltage range (2.7V to 5.5V) make it suitable for loop-powered transmitters. The integrated oscillator reduces component count, simplifying design in space-constrained field instruments. With a data rate of 1200 bps, it provides reliable digital communication for configuration and diagnostics without disrupting analog measurement signals.

Smart Transmitters
The AD5700-1BCPZ-RL is specifically designed for smart transmitters that need HART communication. Its integrated receive band-pass filter and internally buffered HART output provide high drive capability, ensuring signal integrity over long cable runs. The device's low power-down current (1 µA) is critical for loop-powered transmitters where power budget is tight. The compact 24-lead LFCSP package fits easily into small transmitter housings, and the integrated oscillator eliminates the need for an external crystal, reducing BOM cost and board space.
Recommended
Valve Positioners
The AD5700-1BCPZ-RL is well-suited for valve positioners that require HART communication for remote calibration and diagnostics. Its low supply current of 86 µA in listen mode allows it to be powered from the 4-20 mA loop without affecting the analog signal. The integrated oscillator ensures accurate timing for FSK modulation, and the device's compliance with the HART physical layer guarantees interoperability with existing HART masters. The small LFCSP package is ideal for the compact form factor of modern valve positioners.
Recommended
Field Instruments
The AD5700-1BCPZ-RL is a key component in field instruments such as pressure, temperature, and flow transmitters. Its integrated functions reduce external component count, enhancing reliability in harsh industrial environments. The device operates from 2.7V to 5.5V, accommodating various power supply designs. The power-down mode with 1 µA current is beneficial for battery-powered instruments. The HART modem enables digital communication for remote monitoring and configuration, improving overall system efficiency.
Recommended
Process Automation
In process automation, the AD5700-1BCPZ-RL enables HART communication in distributed control systems. Its low power consumption and small footprint make it ideal for integration into existing 4-20 mA loops. The device's integrated receive filter and buffered output ensure robust communication in noisy industrial environments. The 1200 bps data rate is sufficient for transmitting process variables and diagnostic information. The AD5700-1 is designed to interface easily with Analog Devices' industrial converters, enabling complete smart transmitter solutions.
Recommended
Remote Monitoring
The AD5700-1BCPZ-RL is suitable for remote monitoring applications where HART communication is used to transmit data from field devices to a central control room. Its low power consumption allows operation from battery or loop power, making it ideal for remote locations. The integrated oscillator and minimal external components simplify design and improve reliability. The device's compliance with HART physical layer ensures compatibility with existing infrastructure.

Key Differentiators
- Integrated oscillator eliminates external crystal (vs AD5700BCPZ-R5)
- Industrial temperature range up to +125°C (vs AD5700-1ACPZ-RL7)
- Low power-down current of 1 µA (vs AD5700BCPZ-R5)
Design Notes
The AD5700-1BCPZ-RL operates from 2.7V to 5.5V. For loop-powered applications, ensure the supply voltage remains above the minimum dropout of the loop-powered regulator. Use a 0.1 µF decoupling capacitor close to the VCC pin and a 10 µF bulk capacitor for low-frequency stability. In power-down mode, the RESET pin should be held low to reduce current to 1 µA.
Follow the recommended layout in the AD5700/AD5700-1 datasheet. Keep the HART_IN and HART_OUT traces short and shielded to minimize noise coupling. Place the receive band-pass filter components close to the HART_IN pin. Use a solid ground plane under the LFCSP package to enhance thermal performance and reduce parasitic inductance.
Do not exceed the absolute maximum supply voltage of 6V. Ensure the RESET pin is properly pulled high during normal operation; otherwise, the device may enter power-down mode unexpectedly. If using the internal reference, tie REF_EN to RESET to power down both together. Verify that the HART output is properly terminated to avoid signal reflections.
