Overview
The AD5752AREZ is a dual, 16-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 analog and 2.7 V to 5.5 V digital. The device features software-programmable output ranges including ±10 V and ±10.8 V. Key electrical specifications include a maximum integral nonlinearity (INL) of ±16 LSB, a typical settling time of 10 μs, and integrated reference buffers. It utilizes an iCMOS process technology and communicates via a DSP/microcontroller-compatible serial interface.
Feature Summary
- Dual-channel 16-bit resolution with guaranteed monotonicity
- Software-selectable unipolar/bipolar output ranges (+5 V, +10 V, +10.8 V, ±5 V, ±10 V, ±10.8 V)
- Integrated reference buffers and power-up/power-down 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 (PLCs)
Procurement Notes
Verify the specific suffix 'AREZ' corresponds to the industrial temperature grade (-40°C to +85°C) and TSSOP-24 package variant. Confirm that the external reference voltage source matches the required 2 V to 3 V input range for specified performance. Ensure supply voltages remain within the absolute maximum ratings of AVDD/AVSS ±16.5 V and DVCC 5.5 V during operation.
Selection Notes
Select the AD5752AREZ when 16-bit resolution and low INL error (±16 LSB max) are required for precision applications. Choose this component over the AD5722 or AD5732 if higher resolution is necessary. Consider the dual-channel architecture for space-constrained designs requiring simultaneous updates. Verify compatibility with the system's serial clock rates up to 30 MHz and digital logic levels.
Part Context
The AD5752AREZ belongs to the AD5722/AD5732/AD5752 family of complete, serial input DACs. It shares pinout and functional compatibility with the quad-channel variants AD5724/AD5734/AD5754. The 'A' version denotes specific accuracy grades compared to the 'B' version, while 'REZ' indicates the TSSOP package and RoHS compliance. This part is manufactured using Analog Devices' iCMOS process technology.
Replacement Considerations
The AD5752AREZ-REEL7 is a reel-packaged equivalent of the same device. For quad-channel requirements, the AD5754AREZ offers identical performance across four channels. Single-channel alternatives like the AD9752ARZ provide different architectures but lack the dual-channel voltage output configuration.
