DAC5571IDBVTG4

Digital To Analog Converters Overview

The DAC5571IDBVTG4 is a low-power, single-channel, 8-bit buffered voltage output digital-to-analog converter (DAC) manufactured by Texas Instruments. It features an on-chip precision output amplifier capable of rail-to-rail output swing. The device utilizes an I2C-compatible two-wire serial interface with clock rates up to 3.4 Mbps. Integrated power-on reset circuitry ensures the DAC output initializes at zero volts upon power-up. The component operates within an analog and digital supply voltage range of 2.7 V to 5.5 V. Key electrical parameters include a sampling rate of 188 kS/s, a settling time of 8 µs, and a typical operating current of 155 µA. Differential nonlinearity is specified at ±0.25 LSB maximum, while integral nonlinearity is ±1 LSB maximum.

Digital To Analog Converters Procurement Notes

Verify the suffix 'G4' indicates compliance with RoHS 3 standards and lead-free manufacturing specifications. Confirm the package designation corresponds to the SOT-23-6 surface-mount form factor. Ensure the ordering part number matches the specific tape-and-reel packaging configuration required for automated assembly processes.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 8-bit resolution is sufficient for the application requirements. Consider the 2.7 V to 5.5 V supply range compatibility with standard logic levels. Evaluate the 188 kS/s update rate against system bandwidth needs. Verify that the SOT-23-6 package dimensions fit the available PCB real estate constraints.

Digital To Analog Converters Part Context

This device belongs to the DAC5571 family, which includes variants with different resolutions such as the 10-bit DAC6571 and 12-bit DAC7571. The IDBVTG4 designation specifically identifies the 8-bit version in a SOT-23-6 package with tape-and-reel packaging and green (RoHS compliant) material composition. It shares the same core architecture and interface protocols as other members of this series.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible alternatives within the same family include the DAC5571IDBVR and DAC5571IDBVT. For higher resolution requirements, consider the DAC6571 or DAC7571 series. Multi-channel applications may require the quad-channel DAC5574 or DAC6574 variants.
