DAC5578SPWR

Digital To Analog Converters Overview

The DAC5578SPWR is an octal, 8-bit digital-to-analog converter manufactured by Texas Instruments. It features eight voltage-buffered outputs and operates on a single supply ranging from 2.7 V to 5.5 V for both analog and digital domains. The device utilizes a 2-wire I2C-compatible serial interface with a maximum sampling rate of 55.55 kS/s. Key performance metrics include a settling time of 12 µs, integral nonlinearity (INL) of ±0.01 LSB, and differential nonlinearity (DNL) of ±0.01 LSB. It 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

• Integrates eight independent 8-bit DAC channels with built-in voltage buffers for direct drive capability.
• Supports standard 2-wire I2C serial communication interface for simplified system connectivity.
• Provides reset functionality to mid-scale output levels upon power-up or system reset events.

Digital To Analog Converters Applications

• Multi-channel process control systems requiring isolated analog outputs.
• Portable instrumentation utilizing low-voltage single-supply operation.
• Industrial automation interfaces needing multiple simultaneous analog signal generation.

Digital To Analog Converters Procurement Notes

Verify the specific suffix SPWR against the manufacturer's current datasheet to confirm the TSSOP-16 packaging and commercial grade specifications. Ensure compatibility with the target I2C bus voltage levels and check for any recent design changes or lifecycle notices associated with this part number before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when eight independent 8-bit analog outputs are required in a compact surface-mount footprint. It is suitable for applications prioritizing low power consumption and wide operating temperature ranges over high-resolution precision. Compare INL/DNL specifications against system requirements to ensure adequate linearity for the intended signal processing tasks.

Digital To Analog Converters Part Context

This device belongs to the DAC5578 family of octal digital-to-analog converters. It shares architectural similarities with higher-resolution variants such as the DAC6578 (10-bit) and DAC7578 (12-bit), which offer improved linearity at potentially different power profiles. All members of this series maintain the same pinout and interface compatibility, facilitating scalable design transitions.

Digital To Analog Converters Replacement Considerations

The DAC5578SPW serves as a parameter-equivalent alternative offering the same electrical characteristics but packaged in a TSSOP-16 tube instead of a reel. Verify that the change in packaging format aligns with existing assembly equipment capabilities and board layout constraints.
