DAC6578SPWR

Digital To Analog Converters Overview

The DAC6578SPWR is an octal digital-to-analog converter manufactured by Texas Instruments, featuring a 10-bit resolution and eight independent voltage-output channels. It operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. The device utilizes a 2-Wire I2C compatible interface for data input and communication. 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. Integral nonlinearity (INL) is specified at ±0.25 LSB, while differential nonlinearity (DNL) is ±0.03 LSB. It is housed in a 16-pin TSSOP package and supports an operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Octal architecture providing eight independent buffered voltage outputs within a compact surface-mount package.
• Ultra-low glitch impulse characteristics designed to minimize transient spikes during code transitions.
• Integrated reset function that forces all outputs to mid-scale upon initialization or system reset events.
• Cost-optimized design with low power consumption suitable for battery-operated and space-constrained applications.

Digital To Analog Converters Applications

• Programmable gain amplifiers requiring multi-channel signal conditioning
• Portable instrumentation systems needing low-power analog output
• Process control loops utilizing multiple isolated voltage references

Digital To Analog Converters Procurement Notes

Verify the suffix 'R' indicates tape-and-reel packaging rather than tube packaging when sourcing this specific part number. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification. Cross-reference the exact datasheet revision to validate pinout and electrical specifications against current design requirements.

Digital To Analog Converters Selection Notes

Select the DAC6578SPWR when eight simultaneous 10-bit voltage outputs are required with minimal board space. Compare against the DAC7578SPWR if higher 12-bit resolution is necessary, noting potential differences in DNL performance. Consider the DAC5578SPWR for applications prioritizing lower cost over 10-bit precision. Verify that the I2C address configuration meets system bus constraints and that the 12 µs settling time satisfies loop bandwidth requirements.

Digital To Analog Converters Part Context

This component belongs to the DACx578 family of octal digital-to-analog converters from Texas Instruments. The family shares identical pinouts, interfaces, and mechanical dimensions across varying resolutions (8-bit, 10-bit, and 12-bit). This specific model represents the 10-bit variant, positioned between the 8-bit DAC5578 and the 12-bit DAC7578 in terms of performance and accuracy specifications.

Digital To Analog Converters Replacement Considerations

DAC6578SPW serves as the tube-packaged equivalent with identical electrical characteristics. DAC7578SPWR offers 12-bit resolution with a pin-compatible form factor but exhibits different DNL specifications. DAC5578SPWR provides 8-bit resolution as a cost-down alternative within the same package.
