AD5347BRU-REEL7

Digital To Analog Converters Overview

The AD5347BRU-REEL7 is an octal 10-bit digital-to-analog converter (DAC) from Analog Devices, operating on a single 2.5 V to 5.5 V supply. It features a parallel interface with double-buffered input registers and simultaneous update capability via the LDAC pin. The device includes rail-to-rail buffered outputs, power-on reset to 0 V, and asynchronous clear functionality. Key electrical parameters include a typical settling time of 9 µs, relative accuracy of ±0.5 LSB, and differential nonlinearity of ±0.05 LSB. It supports GAIN pin selection for output ranges of 0 V to VREF or 0 V to 2 × VREF.

Digital To Analog Converters Feature Summary

• Octal 10-bit resolution with rail-to-rail buffered voltage outputs
• Parallel interface with double-buffered input registers and simultaneous update
• Low power consumption: 1.4 mA max in normal mode; power-down current as low as 120 nA at 3 V
• Guaranteed monotonic by design over all codes

Digital To Analog Converters Applications

• Portable battery-powered instruments
• Digital gain and offset adjustment systems
• Programmable voltage and current sources
• Optical networking equipment
• Automatic test equipment

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix REEL7 indicates tape-and-reel packaging when sourcing. Confirm the B version temperature range covers the intended operational environment of –40°C to +105°C. Ensure the parallel interface requirements match the host system's data bus capabilities.

Digital To Analog Converters Selection Notes

Select this component for applications requiring multiple independent voltage outputs with moderate precision. The parallel interface necessitates more pins than serial alternatives but offers higher throughput. Consider the 38-lead TSSOP package constraints for PCB layout. Verify that the required output drive current stays within the 25 mA short-circuit limit at 5 V.

Digital To Analog Converters Part Context

The AD5347 is part of the AD5346/AD5347/AD5348 family, which shares pin compatibility across 8-bit, 10-bit, and 12-bit resolutions. This allows designers to upgrade resolution without redesigning the circuit board. The BRU suffix denotes the 38-lead TSSOP package variant.

Digital To Analog Converters Replacement Considerations

Pin-compatible substitutes within the same family include the AD5346 (8-bit) and AD5348 (12-bit). These parts share identical pinouts and interface logic, differing only in resolution and linearity specifications.
