Key Differentiators
- 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)
Design Notes
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.
