AD5725BRSZ-1REEL

Overview

The AD5725BRSZ-1REEL is a quad, 12-bit parallel input voltage output digital-to-analog converter (DAC) from Analog Devices. It features guaranteed monotonicity with ±0.5 LSB maximum integral nonlinearity (INL) and ±1 LSB maximum differential nonlinearity (DNL). The device supports unipolar or bipolar operation using external reference inputs VREFP and VREFN, allowing flexible output range configuration. Key performance metrics include a maximum settling time of 10 µs for a 10 V step and power dissipation under 270 mW with ±15 V supplies. It operates within an industrial temperature range of −40°C to +85°C.

Feature Summary

• Quad-channel architecture with double-buffered inputs and simultaneous updating via LDAC
• ±0.5 LSB max INL error and ±1 LSB max DNL error ensuring high accuracy
• Asynchronous CLR function resets DAC registers to zero scale (0x000) or midscale (0x800)
• Parallel interface with readback capability on data bits

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 '1' in the part number AD5725BRSZ-1REEL against official documentation to confirm the asynchronous CLR reset behavior. Standard AD5725 variants may default to different reset states. Confirm package type SSOP-28 and reel packaging specifications match design requirements before procurement.

Selection Notes

Select this component when four independent 12-bit outputs are required with parallel interface compatibility. Ensure supply voltages align with the +5 V to ±15 V operating range. Verify that the external reference current capabilities meet the sink/source requirements of the VREFP pin, as it is code-dependent. Consider thermal management if operating near the maximum power dissipation limit.

Part Context

The AD5725 belongs to the AD5725 family of high-performance DACs utilizing iCMOS process technology. This technology enables operation at higher voltage levels while reducing power consumption. The B grade designation indicates tighter accuracy specifications compared to the A grade variant. The RSZ suffix denotes the RoHS-compliant SSOP-28 package.
