DAC5578SRGER

Digital To Analog Converters Overview

The DAC5578SRGER is an octal, 8-bit digital-to-analog converter manufactured by Texas Instruments. It features a voltage-buffered output architecture 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 for data input. 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. Nonlinearity specifications are defined by a differential nonlinearity (DNL) of ±0.01 LSB and integral nonlinearity (INL) of ±0.25 LSB. It functions within a temperature range of -40°C to +125°C and is housed in a 24-pin VQFN package.

Digital To Analog Converters Feature Summary

• Integrates eight independent 8-bit DAC channels with internal voltage buffers for direct drive capability.
• Supports standard two-wire I2C serial communication interface for simplified system connectivity.
• Includes a reset function that forces all outputs to mid-scale upon initialization or fault conditions.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Portable instrumentation utilizing battery-powered architectures
• Automotive sensor interface circuits

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'GER' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and moisture sensitivity level. Ensure the ordering part number matches the exact pinout and electrical characteristics required for the target design, as suffix variations may indicate different packaging or environmental ratings without altering core functionality.

Digital To Analog Converters Selection Notes

Select this component when an application demands multiple low-resolution voltage outputs controlled via a minimal pin-count serial bus. The wide operating voltage range and extended temperature specification make it suitable for harsh environments. Compare DNL and INL values against system accuracy requirements to ensure the 8-bit resolution meets the necessary signal fidelity standards.

Digital To Analog Converters Part Context

This device belongs to the DAC5578 family, which shares architectural similarities with higher-resolution variants like the DAC6578 and DAC7578. These components utilize a common resistor-string DAC architecture and offer identical pinouts and interface protocols, allowing for potential design flexibility across different resolution requirements within the same product line.

Digital To Analog Converters Replacement Considerations

The DAC5578SRGET serves as a functional equivalent with identical electrical specifications but differs in packaging format. Verify compatibility with existing PCB footprints if substituting between reel and cut-tape variants.
