Typical Applications
AD5700-1BCPZ is suitable for 6 applications: Industrial Process Control, Smart Transmitters, Valve Positioners, Field Instruments, Loop-Powered Devices, HART Communication Modules.
Industrial Process Control
The AD5700-1BCPZ is ideal for industrial process control systems that use HART communication over 4-20 mA loops. Its low power consumption (1 mA typical) and wide supply range (2.7V to 5.5V) make it suitable for loop-powered transmitters. The integrated oscillator and filter reduce external components, simplifying design and improving reliability in harsh industrial environments.
Recommended
Smart Transmitters
Smart transmitters in process automation use HART to communicate digital data over analog loops. The AD5700-1BCPZ's small 4x4 mm LFCSP package and internal oscillator make it ideal for compact transmitter designs. Its high output drive capability ensures reliable signal transmission over long cable runs, while the integrated receive filter improves noise immunity.
Recommended
Valve Positioners
Valve positioners require precise control and communication with control systems. The AD5700-1BCPZ provides reliable HART communication with low power consumption, making it suitable for loop-powered positioners. Its integrated functions reduce external component count, which is critical in the limited space of a valve positioner housing.
Recommended
Field Instruments
Field instruments such as pressure, temperature, and flow transmitters often use HART for configuration and diagnostics. The AD5700-1BCPZ's low power and small footprint make it ideal for these devices. The internal oscillator eliminates the need for a crystal, reducing cost and improving reliability in vibration-prone environments.
Recommended
Loop-Powered Devices
Loop-powered devices must operate on very low power budgets. The AD5700-1BCPZ's typical supply current of 1 mA is ideal for such applications, as it minimizes the load on the 4-20 mA loop. The wide supply voltage range allows operation from the loop's voltage, and the integrated functions reduce external components, saving space and power.
Recommended
HART Communication Modules
The AD5700-1BCPZ can be used in HART communication modules that interface with legacy instruments. Its compliance with the HART physical layer ensures interoperability with existing HART networks. The integrated filter and oscillator simplify the module design, and the small package allows for high-density integration in multi-channel systems.

Key Differentiators
- Integrated internal oscillator (vs AD5700BCPZ)
- Low power consumption (vs HT5700)
- Proven reliability and support (vs HT5700)
Design Notes
The AD5700-1BCPZ operates from 2.7V to 5.5V. Use a low-dropout regulator to provide a clean supply, and place a 0.1uF decoupling capacitor close to the VDD pin. For loop-powered applications, ensure the supply voltage remains within the specified range even under worst-case loop conditions.
For optimal performance, keep the HART signal traces short and shielded from digital noise. Use a ground plane and place the external components (e.g., coupling capacitor) close to the HART_IN and HART_OUT pins. Follow the layout guidelines in the datasheet to minimize parasitic capacitance and inductance.
Do not exceed the absolute maximum ratings. Ensure the HART signal is properly coupled and protected against overvoltage. If using the AD5700BCPZ (without internal oscillator), ensure the crystal is correctly connected. For the AD5700-1BCPZ, the internal oscillator is factory-trimmed, so no external crystal is needed.
