DAC7578SRGER

Digital To Analog Converters Overview

The DAC7578SRGER is an octal, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a voltage-buffered output architecture and operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. The device supports a 2-Wire I2C compatible interface with four selectable slave addresses. 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 maximum DNL of ±0.1 LSB and INL of ±0.25 LSB. It is housed in a 24-pin VQFN package and functions within a temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Octal channel configuration providing eight independent 12-bit voltage outputs
• Integrated reset function that forces outputs to mid-scale upon power-up or system reset
• Low-power operation optimized for battery-driven applications with minimal current draw
• Compact surface-mount packaging designed to minimize printed circuit board area

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Portable instrumentation utilizing low-voltage single-supply architectures
• Data acquisition systems needing precise analog reference voltages
• Automotive sensor interfaces operating under extended temperature conditions

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel quantity matches project requirements. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure ESD protection protocols are followed during handling due to the moisture sensitivity level indicated in the datasheet. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and traceability.

Digital To Analog Converters Selection Notes

Select this component when eight simultaneous 12-bit conversions are required within a constrained physical footprint. The I2C interface simplifies microcontroller connectivity compared to parallel alternatives. Consider the 12 µs settling time against system update rates to ensure adequate stability. Evaluate the 2.7 V minimum supply voltage against available power rails to guarantee proper operation across the full industrial temperature range.

Digital To Analog Converters Part Context

This device belongs to the DAC7578 family of octal digital-to-analog converters. It shares core architectural similarities with variants such as the DAC7578SPWR and DAC7578SRGET, differing primarily in packaging style and shipping configuration. The SRGER designation specifically indicates the VQFN-24 form factor supplied in a standard reel format for automated surface-mount assembly processes.

Digital To Analog Converters Replacement Considerations

The DAC7578SPWR serves as a pin-compatible alternative utilizing a TSSOP-16 package. The DAC7578SRGET offers identical electrical characteristics but may differ in reel packaging specifications. Verify pinout compatibility and thermal dissipation requirements when substituting between VQFN and TSSOP footprints.
