Overview
The AD5732AREZ-REEL7 is a dual, 14-bit serial input digital-to-analog converter (DAC) from Analog Devices. It operates from single or dual supplies ranging from +4.5 V to +16.5 V and ±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) of ±4 LSB, a typical settling time of 10 μs, and a total unadjusted error (TUE) of ±0.3% FSR for the A version. It utilizes an iCMOS process and communicates via a DSP-compatible serial interface.
Feature Summary
- Dual-channel 14-bit resolution with guaranteed monotonicity
- Software-selectable unipolar/bipolar output voltage ranges
- Integrated reference buffers and power-up control circuitry
- Simultaneous updating capability via LDAC pin
Applications
- Industrial automation systems
- Closed-loop servo control applications
- Process control instrumentation
- Automotive test and measurement equipment
- Programmable logic controllers
Procurement Notes
Verify the specific revision level (Rev. F datasheet) and package type (24-lead TSSOP) against design requirements. Confirm that the external reference voltage falls within the 2 V to 3 V range for specified performance. Ensure supply voltages remain within absolute maximum ratings to prevent damage.
Selection Notes
Select this component when dual-channel 14-bit precision is required with high-speed settling. Compare INL specifications against the AD5752 (16-bit, ±16 LSB) if higher resolution is needed, or the AD5722 (12-bit, ±1 LSB) if lower cost is prioritized. Verify compatibility with the system's serial clock speed, which supports up to 30 MHz.
Part Context
This part belongs to the AD5722/AD5732/AD5752 family of complete, dual, serial input DACs. It shares pinout and functional architecture with the quad-channel variants (AD5724/AD5734/AD5754). The 'AREZ' suffix indicates the industrial temperature range (-40°C to +85°C) and TSSOP-24 package, while '-REEL7' denotes tape-and-reel packaging.
Replacement Considerations
The AD5722AREZ and AD5752AREZ are pin-compatible alternatives within the same family, offering 12-bit and 16-bit resolutions respectively. For quad-channel requirements, the AD5734AREZ provides equivalent 14-bit performance across four channels.
