Product Overview
The AD5755-1ACPZ-REEL7 is a high-integration 4-channel 16-bit industrial DAC from ADI, optimized for PLC, DCS and HART smart transmitters. Each channel supports independent software-programmable current or voltage output. Integrated dynamic boost power control (DPC) uses on-chip boost converter to cut thermal dissipation under heavy current-loop loads, enabling dense multi-channel PCB layout without extra heat sinks. It embeds 5V low-drift reference, full fault diagnostics (open/short circuit, overtemperature) and dedicated CHART pins for direct HART signal coupling without extra filter circuits. This REEL7 variant ships on 7-inch tape & reel for automated SMT mass assembly, packed in compact 64-LFCSP-VQ exposed pad package.
Core Advantages
Innovative Dynamic Boost Power Control (DPC)
On-chip DC-DC boost converter dynamically adjusts output driver voltage based on real load resistance, reduces internal power loss and heat buildup for tightly stacked multi-channel control modules.
Software-Flexible Multi-Range Output Configurations
4 fully independent channels support programmable current ranges: 0–20mA, 4–20mA, 0–24mA, ±20mA; voltage ranges: 0–5V, 0–10V, ±5V, ±10V via serial register setup.
Full Diagnostic & Circuit Fault Protection
Built-in monitoring detects current-loop open circuits, voltage output short circuits and chip overtemperature, sending fault flags to host controller for fast field fault response.
Native Dedicated HART Signal Coupling Pins
Independent CHART pins on each channel directly inject HART modulation signals onto analog current loops, eliminating complex external passive filter networks required by standard DAC models.

Frequently Asked Questions
Q1: Are stocked AD5755-1ACPZ-REEL7 chips genuine new original?
A: All stock is 100% factory-original new ADI parts, shipped in original anti-static 7-inch tape & reel. Every batch passes visual and solder pin inspection before delivery.
Q2: What is the core difference between AD5755 and AD5755-1?
A: AD5755-1 adds dedicated CHART HART coupling pins and optimized internal signal routing, supporting direct HART modulation onto current loops with minimal external components; standard AD5755 lacks this dedicated HART hardware.
Q3: What does REEL7 suffix mean?
A: REEL7 denotes 7-inch diameter tape & reel packaging, standard format for high-volume automated SMT pick-and-place production lines.
Q4: How does DPC dynamic power control reduce cabinet heat?
A: Traditional DACs waste excess supply voltage across output transistors and generate heavy heat. AD5755-1’s integrated boost DPC dynamically adjusts driver supply voltage to match real load resistance, drastically cutting on-chip power dissipation for dense multi-channel modules.
