Overview
The AD5724AREZ-REEL7 is a quad, 12-bit serial input digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates from single supplies of +4.5 V to +16.5 V or dual supplies of ±4.5 V to ±16.5 V. The device features software-programmable output ranges including +5 V, +10 V, +10.8 V, ±5 V, ±10 V, and ±10.8 V. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±16 LSB, a differential nonlinearity (DNL) error of ±1 LSB, and a typical settling time of 10 µs. It utilizes an iCMOS process technology and communicates via a DSP-compatible serial interface with clock rates up to 30 MHz.
Feature Summary
- Quad-channel 12-bit resolution with guaranteed monotonicity
- Software-selectable unipolar/bipolar output voltage ranges
- Integrated reference buffers and power-up/power-down control circuitry
- Simultaneous updating capability via LDAC pin for all four channels
Applications
- Industrial automation systems
- Closed-loop servo control applications
- Process control instrumentation
- Automotive test and measurement equipment
- Programmable logic controllers (PLCs)
Procurement Notes
Verify the specific suffix 'REEL7' indicates tape-and-reel packaging when sourcing components. Confirm that the A-grade version meets the required Total Unadjusted Error (TUE) specifications of ±0.3% FSR for the ±10 V range. Ensure compatibility with the 24-lead TSSOP footprint during procurement planning.
Selection Notes
Select the AD5724 variant specifically for 12-bit resolution requirements; higher precision needs may require the AD5734 (14-bit) or AD5754 (16-bit). Verify that the system's digital logic levels are compatible with the 2.7 V to 5.5 V DVCC supply range. Consider the thermal impedance of the 24-TSSOP package if operating near the upper limits of the industrial temperature range.
Part Context
This component belongs to the AD5724/AD5734/AD5754 family of complete, serial input DACs. The AD5724 represents the 12-bit resolution tier within this series, sharing identical pinouts, serial interface protocols, and power supply requirements with its 14-bit and 16-bit counterparts. All variants utilize the same 24-lead TSSOP package and iCMOS process technology.
Replacement Considerations
The AD5724AREZ-REEL7 is functionally interchangeable with other AD5724 variants such as the AD5724ARZ or AD5724ARMZ, provided the package type matches the design constraints. Substituting with AD5734 or AD5754 models requires no hardware changes but offers higher resolution.
