DAC5571IDBVRG4

Digital To Analog Converters Overview

The DAC5571IDBVRG4 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 a two-wire I2C-compatible serial interface with clock rates up to 3.4 Mbps. Key electrical parameters include a resolution of 8 bits, a sampling rate of 188 kS/s, and a settling time of 8 µs. It operates on analog and digital supply voltages ranging from 2.7 V to 5.5 V. The component exhibits a differential nonlinearity (DNL) of ±0.25 LSB and an integral nonlinearity (INL) of ±1 LSB. Operating current is 155 µA at 5 V, with power consumption under 400 µW.

Digital To Analog Converters Feature Summary

• Integrated power-on reset circuit ensures the DAC output initializes to zero volts upon power-up until valid write operations occur.
• Dual-buffered input registers facilitate multi-device synchronization within the same system architecture.
• Programmable power-down mode allows significant reduction in current consumption via internal control registers.
• Rail-to-rail output capability provided by the on-chip buffer amplifier supports full-scale voltage utilization.

Digital To Analog Converters Applications

• Process control systems requiring precise analog signal generation
• Data acquisition systems for sensor signal conditioning
• Portable battery-powered instruments due to low power characteristics

Digital To Analog Converters Procurement Notes

Verify the G4 suffix indicates lead-free and RoHS compliance status as per manufacturer specifications. Confirm the SOT-23-6 package dimensions match PCB footprint requirements. Ensure I2C address configuration aligns with system bus constraints, noting support for up to two devices on one bus. Validate operating temperature range suitability for the intended environmental conditions.

Digital To Analog Converters Selection Notes

Select this component for applications demanding high speed relative to resolution, specifically the 188 kS/s update rate. Consider the resistor-string architecture for cost optimization compared to R-2R or sigma-delta types. Evaluate the 8-bit resolution against required accuracy; if higher precision is needed, consider the DAC7571 or DAC8571 series variants. Check pin compatibility if replacing older DAC5571 versions without the G4 suffix.

Digital To Analog Converters Part Context

The DAC5571 belongs to the DAC5571 family of single-channel I2C DACs. It shares architectural similarities with the DAC7571 (12-bit) and DAC6571 (10-bit). Quad-channel variants exist as the DAC5574, DAC6574, and DAC7574. This specific part number represents the 8-bit version in a small SOT-23-6 package optimized for space-constrained designs.

Digital To Analog Converters Replacement Considerations

The DAC5571IDBVR is a compatible alternative within the same series. Verify if the G4 suffix introduces any functional differences beyond material composition. Cross-reference pinouts for other DAC557x family members to ensure mechanical and electrical compatibility during substitution.
