AD5735ACPZ

Overview

The AD5735ACPZ is a quad-channel, 12-bit digital-to-analog converter (DAC) featuring both current and voltage outputs. It operates with analog supplies ranging from −26.4 V to +33 V and a digital supply of 2.7 V to 5.5 V. The device integrates on-chip dynamic power control via a DC-to-DC boost converter to minimize thermal dissipation in current mode. Key specifications include ±0.1% maximum total unadjusted error for current outputs and ±0.09% for voltage outputs. It utilizes a versatile 3-wire serial interface supporting clock rates up to 30 MHz.

Feature Summary

• Quad-channel 12-bit resolution with guaranteed monotonicity
• Integrated DC-to-DC boost converter for dynamic power control
• Configurable current ranges: 0–20 mA, 4–20 mA, 0–24 mA
• Configurable voltage ranges: 0–5 V, 0–10 V, ±5 V, ±10 V

Applications

• Process control systems
• Actuator control loops
• Programmable Logic Controllers (PLCs)

Procurement Notes

Verify the package marking and date code against the manufacturer's ordering guide to confirm authenticity. Ensure the component meets the specified industrial temperature range of −40°C to +105°C if operating in extreme environments. Check for any specific handling requirements related to moisture sensitivity levels as indicated in the datasheet.

Selection Notes

Select this component when multiple isolated analog outputs are required within a single package. The integrated boost converter makes it suitable for applications where thermal management is critical in current output modes. Ensure the external reference voltage matches the internal reference input requirements if higher precision than the on-chip reference is needed.
