DAC5578SPW

Digital To Analog Converters Overview

The DAC5578SPW is an octal, 10-bit digital-to-analog converter manufactured by Texas Instruments. It features a resistor-string architecture with buffered voltage outputs and supports I2C serial communication. The device operates on dual power supplies ranging from 2.7 V to 5.5 V for both analog and digital domains. Key performance metrics include a settling time of 12 µs, a sampling rate of 55.55 kS/s, and low power consumption of 3.4 mW. It exhibits high linearity with INL/DNL specifications of ±0.25/±0.03 LSB and a gain error of 0.15% FSR. The component functions within a temperature range of -40°C to +125°C and is housed in a 16-TSSOP package.

Digital To Analog Converters Feature Summary

• Octal configuration providing eight independent 10-bit channels in a single compact package.
• Integrated reset function that forces all outputs to mid-scale upon initialization or fault conditions.
• Low-power design optimized for battery-operated applications with minimal current draw.
• Cost-optimized solution suitable for space-constrained industrial and consumer systems.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Portable instrumentation and data acquisition devices
• Battery-powered test equipment and measurement tools
• Automotive sensor interface circuits

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'SPW' corresponds to the TSSOP-16 tube packaging variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements against your assembly timeline. Ensure the ordering part number matches the exact pinout and electrical characteristics defined in the official datasheet to avoid integration errors.

Digital To Analog Converters Selection Notes

Select this model when eight simultaneous 10-bit output channels are required with I2C connectivity. Compare against the DAC5578 series if 8-bit resolution suffices for lower cost, or the DAC7578 series for higher precision needs. Evaluate the 12 µs settling time against system bandwidth requirements to ensure adequate response speed for the target application dynamics.

Digital To Analog Converters Part Context

This component belongs to the DAC5578 family of octal DACs, which also includes variants with different resolutions such as the DAC5578 (8-bit) and DAC7578 (12-bit). All members share similar interfaces and power profiles but differ in accuracy and noise performance. The SPW designation specifically identifies the plastic small-outline thin-package version designed for surface-mount technology assembly.

Digital To Analog Converters Replacement Considerations

The DAC5578SPW is parameter-equivalent to the DAC5578SPWR for functional substitution, differing primarily in packaging format (tube versus reel). Direct replacements within the same family include the DAC5578SPW for 8-bit resolution or the DAC7578SPW for 12-bit resolution, provided pin compatibility and performance margins are verified.
