Typical Applications
AD5700-1BCPZ-RL is suitable for 6 applications: Industrial Process Control, Smart Transmitters, Valve Positioners, Field Instruments, HART-to-Wireless Gateways, Process Automation.
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 Β΅A in listen mode) and integrated oscillator make it suitable for loop-powered transmitters, where power is limited. The device's robust FSK modulation ensures reliable data transmission over long cable runs, even in noisy industrial environments. It interfaces seamlessly with ADI's industrial DACs like the AD5421, enabling complete smart transmitter designs.

Smart Transmitters
In smart transmitters, the AD5700-1BCPZ-RL provides the HART modem function, allowing digital configuration and diagnostics over the existing analog loop. Its integrated receive band-pass filter simplifies the analog front-end, reducing external component count. The device's low power-down current (1 Β΅A) is critical for battery-powered or loop-powered operation. The buffered HART output drives the loop directly, eliminating the need for additional buffer amplifiers. This makes the AD5700-1BCPZ-RL a key component in modern field instruments.
Recommended
Valve Positioners
Valve positioners use the AD5700-1BCPZ-RL to receive HART commands for setpoint adjustment and to transmit position feedback. The device's high output drive capability ensures the HART signal is strong enough to travel over the control loop. Its wide supply voltage range (2.7V to 5.5V) accommodates various power architectures. The integrated oscillator reduces component count, which is beneficial in the compact enclosures typical of valve positioners. The device's compliance with HART physical layer ensures interoperability with existing control systems.
Recommended
Field Instruments
Field instruments such as pressure, temperature, and flow transmitters benefit from the AD5700-1BCPZ-RL's low power and small footprint. The device's integrated oscillator eliminates the need for an external crystal, saving board space and cost. Its power-down mode allows the instrument to conserve energy when not communicating. The device's robust design ensures reliable operation in harsh industrial environments, with an operating temperature range of -40Β°C to +125Β°C. This makes it suitable for outdoor and high-temperature applications.
Recommended
HART-to-Wireless Gateways
In HART-to-wireless gateways, the AD5700-1BCPZ-RL acts as the HART modem to interface with legacy wired instruments, converting their signals for wireless transmission. Its low power consumption is essential for battery-powered gateways. The device's integrated filter and signal detection simplify the design, reducing time-to-market. The buffered output allows direct connection to the HART loop without additional components. This enables seamless integration of legacy devices into modern wireless networks.
Recommended
Process Automation
Process automation systems rely on the AD5700-1BCPZ-RL for reliable HART communication in distributed control systems. The device's compliance with HART physical layer ensures compatibility with existing infrastructure. Its low power and small package make it suitable for space-constrained I/O modules. The integrated oscillator reduces BOM cost and complexity. The device's wide temperature range and robust design ensure long-term reliability in demanding industrial environments.

Key Differentiators
- Integrated oscillator eliminates external crystal (vs AD5700BCPZ-R5)
- Wider temperature range than A-grade variant (vs AD5700-1ACPZ-RL7)
- Low power consumption for loop-powered devices (vs AD5700BCPZ-R5)
Design Notes
The AD5700-1BCPZ-RL operates from 2.7V to 5.5V. Use a low-dropout regulator to provide a clean supply, and place a 0.1 Β΅F decoupling capacitor close to the VCC pin. For loop-powered applications, ensure the supply current (86 Β΅A in listen mode) is within the loop budget. In power-down mode, current drops to 1 Β΅A, which is ideal for battery-powered devices.
Follow the layout guidelines in the AD5700 datasheet (Rev. G). Keep the HART input and output traces short and shielded to minimize noise coupling. Use a solid ground plane and place the decoupling capacitors as close to the pins as possible. The LFCSP package has an exposed pad that should be soldered to the ground plane for thermal and electrical performance.
Do not exceed the absolute maximum ratings, especially on the supply voltage. Ensure the RESET pin is properly pulled high during normal operation; holding it low places the device in power-down mode. If using the internal reference, tie REF_EN to RESET to power down the reference as well. Verify the HART signal levels meet the physical layer specifications to avoid communication errors.
