AD5303BRU-REEL7

Digital To Analog Converters Overview

The AD5303BRUZ-REEL7 is a dual-channel, 8-bit digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.5 V to 5.5 V supply with typical current consumption of 230 μA at 3 V and 300 μA at 5 V. The device features rail-to-rail voltage outputs with a slew rate of 0.7 V/μs and utilizes a high-speed 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 30 MHz. Key specifications include ±0.5 LSB integral nonlinearity (INL), guaranteed monotonicity, and power-down currents as low as 50 nA at 3 V. It is housed in a 16-lead TSSOP package.

Digital To Analog Converters Feature Summary

• Digital gain and offset adjustment
• Programmable voltage and current sources
• Programmable attenuators

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and temperature range. Ensure compatibility with system voltage requirements, as the device operates between 2.5 V and 5.5 V. Confirm that the serial interface timing meets the microprocessor or controller specifications for SYNC, SCLK, and DIN signals.

Digital To Analog Converters Selection Notes

Select this component when dual-channel, low-power voltage generation is required in space-constrained designs. The B-version offers improved linearity accuracy (±0.5 LSB INL) compared to the A-version. Consider the external reference configuration options; the BUF pins allow selection between buffered and unbuffered reference inputs to optimize noise performance or input voltage range.

Digital To Analog Converters Part Context

This part belongs to the AD5303/AD5313/AD5323 family of dual resistor-string DACs. While the AD5303 provides 8-bit resolution, the family also includes the 10-bit AD5313 and 12-bit AD5323 variants. All share the same 16-lead TSSOP footprint and functional architecture, differing primarily in resolution and linearity specifications.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same family include the AD5303ARUZ (A-version) for less stringent linearity requirements, or the AD5313BRUZ/AD5323BRUZ if higher resolution is needed. Verify that the replacement maintains the required serial interface compatibility and power supply range.
