DAC6578SRGER

Digital To Analog Converters Overview

The DAC6578SRGER is an octal, 10-bit digital-to-analog converter manufactured by Texas Instruments. It features a serial I2C interface and voltage-buffered outputs. The device operates on analog and digital supply voltages ranging from 2.7 V to 5.5 V. Key performance parameters include a settling time of 12 µs, a sampling rate of 55.55 kS/s, and a typical operating current of 1.02 mA. Linearity specifications are defined by a differential nonlinearity (DNL) of ±0.03 LSB and an integral nonlinearity (INL) of ±0.25 LSB. The gain error is specified at 0.15% FSR. It is housed in a 24-pin VQFN package and supports an industrial temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Octal architecture providing eight independent 10-bit channels within a single compact package.
• Ultra-low glitch energy design minimizes output transients during code transitions.
• Integrated reset function allows all outputs to return to mid-scale upon power-up or system reset.
• Cost-optimized solution with low power consumption suitable for space-constrained applications.

Digital To Analog Converters Applications

• Process control systems requiring multi-channel signal generation
• Portable instrumentation with battery-powered constraints
• Data acquisition systems needing buffered analog outputs

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'GER' corresponds to the tape-and-reel packaging format intended for automated surface-mount assembly. Confirm that the component meets RoHS compliance requirements for the target market. Ensure the ordering quantity aligns with standard reel sizes to avoid cut-tape premiums if high volume is required. Check for any moisture sensitivity level restrictions during storage and handling prior to soldering.

Digital To Analog Converters Selection Notes

Select this model when eight simultaneous 10-bit conversions are necessary without occupying excessive board area. Compare against the DAC5578 for higher resolution needs or the DAC7578 for improved linearity if budget permits. Ensure the I2C bus speed compatibility matches the host controller capabilities. Verify that the 2.7 V minimum supply voltage aligns with the system's available power rails.

Digital To Analog Converters Part Context

This component belongs to the DAC6578 family, which shares core electrical characteristics but differs primarily in packaging options. The SRGET variant denotes the reeled version of the SRGER part, often used interchangeably depending on distributor inventory. It serves as a bridge between lower-resolution octal DACs and higher-performance single-channel devices, offering a balance of channel count and precision.

Digital To Analog Converters Replacement Considerations

The DAC6578SPW is a pin-compatible alternative available in a TSSOP-16 package. For applications requiring higher resolution, the DAC7578 series offers 12-bit accuracy with similar form factors. Direct substitution requires verifying that the thermal dissipation limits of the new package type are not exceeded in the existing enclosure design.
