Product Overview

The AD5700-1ACPZ-RL7 is a fully integrated HART® -compliant FSK half - duplex modem from Analog Devices, optimized for low - power industrial applications. Designed for seamless integration into 4 mA to 20 mA loop - powered systems, this compact 24 - lead LFCSP (4 mm × 4 mm) device combines precision signal processing, ultra - low power consumption, and HART Physical Layer compliance. It supports both master and slave configurations, making it ideal for industrial automation, process control, and smart field instruments.

Key Features

HART Physical Layer Compliance

• Integrated FSK modulation/demodulation, carrier detection, and filtering functions, fully compliant with HART Revision 8.1.

Ultra - Low Power Operation

• Receive Mode: 115 μA max supply current (external clock).
• Transmit Mode: 260 μA max supply current (external clock).
• Power - Down Mode: 35 μA max current.

Low-Power Design

• Multi-Power Modes: Sleep, Deep-sleep, Power-down, and Deep-power-down modes reduce power consumption; typical active mode current as low as 200 μA/MHz.
• Wide Voltage Range: Operates from 2.4V to 3.6V, suitable for battery-powered and low-voltage applications.

Flexible Clocking Options

• External crystal (3.6864 MHz), CMOS clock, or precision internal RC oscillator (AD5700 - 1 only).Configurable CLKOUT for system synchronization.

Industrial Robustness

• Wide Temperature Range: -40°C to +125°C.
• High ESD Protection: 8 kV HBM rating.
• AEC - Q100 qualified for harsh environments.

Simplified Design

• Minimal external components required.
• Integrated band - pass filter and buffered HART_OUT output.
• Supports full - duplex operation for system diagnostics.

Versatile Interfaces

• UART interface (TXD, RXD, RTS, CD).
• Compatible with 1.71 V to 5.5 V logic levels

Technical Specifications

Typical Applications
