AD5318ARUZ-REEL7

Digital To Analog Converters Overview

The AD5318ARUZ-REEL7 is an octal 10-bit buffered voltage output digital-to-analog converter (DAC) housed in a 16-lead TSSOP package. It operates from a single 2.5 V to 5.5 V supply, consuming 0.7 mA typical current at 3 V. The device features on-chip rail-to-rail output buffer amplifiers with a slew rate of 0.7 V/μs and supports clock rates up to 30 MHz via a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards. Key electrical specifications include ±4 LSB INL for the A version, a settling time of 9 μs, and power-down currents as low as 120 nA at 3 V.

Digital To Analog Converters Feature Summary

• Octal 10-bit resolution with resistor-string architecture and guaranteed monotonicity by design
• On-chip rail-to-rail output buffer amplifiers allowing full-scale swing with 0.7 V/μs slew rate
• Versatile 3-wire serial interface supporting SCLK rates up to 30 MHz
• Low power operation with individual channel power-down capability reducing current to 120 nA at 3 V

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'REEL7' against the manufacturer's ordering guide to confirm tape-and-reel packaging quantities. Ensure the 'A' version designation matches the required ±4 LSB INL specification rather than the 'B' version's tighter tolerance. Confirm RoHS compliance status and automotive qualification requirements if applicable to the target environment.

Digital To Analog Converters Selection Notes

Select this component when eight independent 10-bit voltage outputs are required in a compact 16-lead TSSOP footprint. The A version provides ±4 LSB INL, suitable for general-purpose applications where the B version's ±3 LSB is not strictly necessary. Consider the external reference configuration options (buffered, unbuffered, or VDD) to optimize system noise and power consumption.

Digital To Analog Converters Part Context

This part belongs to the AD5308/AD5318/AD5328 family of nanoDACs, sharing identical pinouts and functionality across 8-, 10-, and 12-bit resolutions. The AD5318 specifically bridges the gap between the 8-bit AD5308 and 12-bit AD5328, offering higher precision without increasing package size or redesigning the PCB layout.

Digital To Analog Converters Replacement Considerations

The AD5318BRUZ-REEL7 serves as a direct functional replacement with improved linearity (±3 LSB INL). For lower resolution needs, the AD5308ARUZ-REEL7 is compatible; for higher resolution, the AD5328ARUZ-REEL7 shares the same pinout.
