Product Overview
The AD5700-1BCPZ-RL7 is a highly integrated single-chip HART physical layer modem from Analog Devices. It conforms fully to HART physical layer standards, built with an internal 0.5% precision oscillator to eliminate external crystal components, saving PCB space and costs. Operating at 1.71V–5.5V, it integrates receiving band-pass filtering and stable transmitting waveform shaping circuits. With ultra-low active & standby current consumption, it is ideal for 4–20mA loop-powered smart transmitters and industrial handheld communicators.
Core Advantages
Integrated High-Precision Oscillator
The built-in 0.5% accurate clock oscillator meets all HART timing requirements, no external crystal or resonator needed.
Ultra Low Power Consumption
Only 115µA receiving current and 1.5µA standby current, maximizing power budget for loop-powered 4–20mA sensors.
On-Chip Analog Receive Filter
Built-in band-pass filter suppresses out-of-band noise, delivers error-free HART signal decoding under harsh EMI industrial environments.
Wide Supply & Interface Compatibility
1.71V to 5.5V flexible power range, independent Vcc_IO pin supports direct connection with 1.8V / 3.3V / 5V MCUs without level shift circuits.

Frequently Asked Questions
Q1: What is the difference between AD5700 and AD5700-1?
A1: AD5700-1 integrates a 0.5% precision internal oscillator without external crystal. Standard AD5700 needs external clock components.
Q2: What does suffix -RL7 stand for?
A2: It stands for 7-inch tape & reel packing, 1500pcs per reel, suitable for automated SMT production lines.
Q3: Why low operating current matters for 4-20mA loop sensors?
A3: Loop devices have strict residual current limits below 4mA. 115µA working current saves power for other circuit modules.
Q4: How does AD5700-1 suppress out-of-band noise?
A4: Built-in band-pass filter eliminates mains hum and switching noise, ensuring stable HART communication in harsh industrial EMI environments.
Q5: What supply voltage range does AD5700-1 support?
A5: Wide 1.71V to 5.5V supply, independent Vcc_IO pin connects 1.8V/3.3V/5V MCUs directly.
