AD5700-1BCPZ-R5 Übersicht
A HART modem is a specialized integrated circuit that enables digital communication over legacy 4-20 mA analog instrumentation loops. It uses Frequency Shift Keying (FSK) to superimpose digital signals on the analog current loop, allowing simultaneous analog and digital communication. The AD5700-1BCPZ-R5 is part of the broader category of industrial communication ICs, which are essential for smart field instruments, process control, and factory automation systems.
Key features include a low power consumption of 0.86 mA typical in operating mode, a wide supply voltage range of 2.7V to 5.5V, and an integrated 0.5% accurate oscillator. The device supports HART FSK signaling at 1200 baud and includes a UART interface for easy connection to microcontrollers. It also features a carrier detect output and a modem reset function, simplifying system design.
The AD5700-1BCPZ-R5 uses a mixed-signal architecture that combines analog front-end filtering with digital demodulation, ensuring robust performance in noisy industrial environments. The integrated oscillator reduces component count and improves reliability, while the low power consumption makes it suitable for loop-powered devices. The device is specified over the industrial temperature range of -40°C to +125°C.
Typical applications include smart transmitters, valve positioners, flow meters, and other HART-enabled field instruments. It is also used in HART multiplexers and gateway modules for process control systems. The device's low power and small footprint make it ideal for loop-powered 4-20 mA transmitters.
When designing with the AD5700-1BCPZ-R5, ensure proper decoupling of the power supply and careful layout of the analog front-end to minimize noise. The integrated oscillator eliminates the need for an external crystal, but the supply voltage must be kept within the specified range to maintain oscillator accuracy.

Wichtigste Unterscheidungsmerkmale
- Integrated oscillator eliminates external crystal (vs. AD5700BCPZ-R5)
- Low power consumption of 0.86 mA typical (vs. HT5700)
- Wide industrial temperature range of -40°C to +125°C (vs. AD5700-1ACPZ)
Designhinweise
Ensure proper decoupling of the VDD pin with a 0.1uF ceramic capacitor placed as close to the pin as possible. A 10uF bulk capacitor may be needed if the supply is noisy. The AD5700-1BCPZ-R5 operates from 2.7V to 5.5V, so verify the supply voltage is within this range to maintain oscillator accuracy and reliable HART communication.
Careful layout of the analog front-end is essential to minimize noise. Keep the MOD_IN and MOD_OUT traces short and shielded if possible. Use a ground plane to reduce interference. The integrated oscillator eliminates the need for an external crystal, but ensure the supply voltage is stable to maintain oscillator accuracy.
Do not exceed the maximum supply voltage of 5.5V. Ensure the UART interface is properly configured for 1200 baud. The carrier detect output should be monitored to manage communication timing. Avoid placing the device near high-frequency switching regulators without proper filtering, as this can degrade HART signal quality.
