AD5735ACPZ-REEL7

Overview

The AD5735ACPZ-REEL7 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 digital logic from 2.7 V to 5.5 V. The device integrates dynamic power control via an on-chip DC-to-DC boost converter, regulating output driver voltage between 7.4 V and 29.5 V to minimize thermal dissipation. Key electrical specifications include a maximum total unadjusted error (TUE) of ±0.1% for current modes and ±0.09% for voltage modes. It supports serial interfaces up to 30 MHz and includes user-programmable offset and gain adjustments.

Feature Summary

• Quad-channel architecture with 12-bit resolution and guaranteed monotonicity.
• Integrated dynamic power control using a DC-to-DC boost converter for thermal management.
• Versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards.
• On-chip reference with ±10 ppm/°C maximum temperature coefficient.

Applications

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

Procurement Notes

Verify the REEL7 suffix indicates tape-and-reel packaging when sourcing components. Confirm that the specific lot meets industrial temperature range requirements (-40°C to +105°C). Ensure compatibility with the required supply voltages, specifically the AVDD and AVSS ranges necessary for the integrated boost converter operation.

Selection Notes

Select this component for applications requiring simultaneous voltage and current outputs in a single package. The internal RSET option simplifies design but offers higher drift compared to external precision resistors. Consider the 64-lead LFCSP package thermal characteristics and ensure adequate PCB copper area for heat dissipation given the 28 °C/W junction-to-air thermal resistance.

Part Context

The AD5735 belongs to Analog Devices' high-performance DAC family, designed for robust industrial environments. It serves as a versatile solution for multi-channel signal generation where space and power efficiency are critical constraints. The device complements other Analog Devices products such as the AD5755 series and ADR445 precision references.

Replacement Considerations

The AD5737 is listed as a companion product within the same family. Verify pinout and register compatibility before substitution. Other members like the AD5755 may offer different channel counts or resolutions but require validation against specific interface and performance requirements.
