AD5304BRMZ-REEL

Digital To Analog Converters Overview

The AD5304BRMZ-REEL is a quad 8-bit buffered voltage-output digital-to-analog converter (DAC) in a 10-lead MSOP package. It operates from a single 2.5 V to 5.5 V supply, consuming 500 μA at 3 V and reducing to 80 nA in power-down mode. The device features rail-to-rail output buffer amplifiers with a slew rate of 0.7 V/μs and a settling time of 6 μs. It utilizes a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. The B version guarantees ±0.625 LSB integral nonlinearity (INL) and ±0.02 LSB differential nonlinearity (DNL).

Digital To Analog Converters Feature Summary

• Quad 8-bit resolution with guaranteed monotonicity by design.
• Rail-to-rail output swing with 0.7 V/μs slew rate.
• Low power consumption: 500 μA normal, 80 nA power-down.
• B version accuracy: ±0.625 LSB INL, ±0.02 LSB DNL.

Digital To Analog Converters Applications

• Portable battery-powered instruments
• Digital gain and offset adjustment
• Programmable voltage and current sources

Digital To Analog Converters Procurement Notes

Verify the 'B' suffix indicates the ±0.625 LSB INL specification variant. Confirm the REEL suffix corresponds to tape-and-reel packaging for automated assembly. Ensure the MSOP-10 package matches the target PCB footprint requirements.

Digital To Analog Converters Selection Notes

Select this component when four independent 8-bit voltage outputs are required in a compact 10-lead package. The B version is suitable for applications demanding tighter linearity than the A version. Verify that the external reference voltage falls within the 0.25 VDD to VDD input range.

Digital To Analog Converters Part Context

This part belongs to the AD5304/AD5314/AD5324 family of quad DACs. The AD5304 specifically provides 8-bit resolution, while the AD5314 offers 10 bits and the AD5324 offers 12 bits. All share the same pinout and serial interface architecture.

Digital To Analog Converters Replacement Considerations

The AD5304ACPZ is a lead-free LFCSP alternative. The AD5304ARMZ is an SOIC-10 variant. Cross-package replacements require schematic and layout modifications.

Digital To Analog Converters FAQ

What is the maximum serial clock frequency?

The 3-wire serial interface supports clock rates up to 30 MHz.

How does the power-on reset function behave?

The device powers up with both input and DAC registers filled with zeros, ensuring the outputs start at 0 V until a valid write sequence occurs.

Can all four DAC outputs be updated simultaneously?

Yes, the LDAC bit in the serial interface allows for simultaneous updating of all DAC registers and outputs.
