AD5752RBREZ-REEL7

Overview

The AD5752RBREZ-REEL7 is a dual, 16-bit serial input voltage output digital-to-analog converter (DAC) from Analog Devices. It operates from single or dual supplies ranging from +4.5 V to +16.5 V or ±4.5 V to ±16.5 V. The device features an integrated 2.5 V reference with a maximum temperature coefficient of 5 ppm/°C and offers software-programmable output ranges including ±10 V and ±5 V. Key electrical specifications include a maximum integral nonlinearity (INL) of ±16 LSB, a typical settling time of 10 μs, and a power dissipation of 190 mW at ±16.5 V operation. It utilizes a DSP-compatible serial interface and is housed in a 24-lead TSSOP package.

Feature Summary

• Dual-channel 16-bit resolution with guaranteed monotonicity
• Integrated 2.5 V reference buffer with ±5 ppm/°C temperature coefficient
• Software-selectable unipolar/bipolar output ranges (+5 V, +10 V, ±5 V, ±10 V)
• Simultaneous updating capability via LDAC pin for synchronized multi-channel systems

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 ordering suffix REEL7 corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the B-version performance characteristics align with design requirements, as AC parameters are guaranteed by characterization rather than production testing. Ensure compatibility with the host microcontroller's serial interface timing constraints.

Selection Notes

Select this component when dual-channel precision is required with high voltage swing capabilities up to ±16.5 V. The internal reference simplifies board layout compared to external reference designs. Consider the 3-wire serial interface speed limits (up to 30 MHz) when designing communication buses. Verify that the 24-lead TSSOP package dimensions fit the available PCB real estate and thermal management strategy.

Part Context

This part belongs to the AD5722R/AD5732R/AD5752R family, which shares identical pinouts and functional architectures across 12-, 14-, and 16-bit resolutions. The AD5752R represents the highest resolution variant in this dual-channel series. It is functionally compatible with the non-R versions (AD5752), though the R-suffix variants include an integrated on-chip reference, whereas the non-R versions require external references.

Replacement Considerations

The AD5752R without the internal reference (AD5752) serves as a direct pin-compatible alternative if an external reference is preferred. For quad-channel configurations requiring the same interface and performance profile, the AD5754R is the appropriate upgrade within the same product family.
