DAC7571IDBVTG4

Digital To Analog Converters Overview

The DAC7571IDBVTG4 is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a resistor-string architecture with a buffered voltage output capable of rail-to-rail operation. The device communicates via a 2-wire I2C interface with clock rates up to 3.4 Mbps. It operates on analog and digital supply voltages ranging from 2.7 V to 5.5 V. Key electrical specifications include a sampling rate of 50 kS/s, a settling time of 10 µs, and a typical operating current of 135 µA. The component supports an industrial temperature range from -40°C to +105°C and is housed in a compact SOT-23-6 surface-mount package.

Digital To Analog Converters Feature Summary

• Integrated buffered output amplifier enables rail-to-rail voltage swing across the full supply range.
• I2C-compatible serial interface allows connection to standard microcontrollers with minimal pin usage.
• Built-in power-on reset circuit ensures the DAC output initializes to zero volts upon startup.
• Configurable power-down mode significantly reduces current consumption for battery-operated applications.

Digital To Analog Converters Applications

• Portable battery-powered instrumentation
• Process control signal generation
• Data acquisition systems
• Closed-loop servo control

Digital To Analog Converters Procurement Notes

Verify the suffix G4 indicates RoHS compliance and lead-free construction as per Texas Instruments standards. Confirm the DBVT designation corresponds to the tape-and-reel packaging format required for automated assembly. Ensure the device grade matches the intended thermal environment, as the ID variant supports extended industrial temperatures. Cross-reference the manufacturer part number with official distributor catalogs to confirm availability and authenticity before procurement.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, high-resolution conversion is required within a limited footprint. The 12-bit resolution provides adequate precision for many general-purpose applications while maintaining low power consumption. The I2C interface simplifies system design by reducing GPIO requirements compared to parallel or SPI alternatives. Consider the 50 kS/s update rate to ensure it meets the dynamic performance needs of the target application without unnecessary overhead.

Digital To Analog Converters Part Context

This part belongs to the DAC7571 family, which includes variants with different resolutions and channel counts. The DAC7571 represents the 12-bit single-channel option within this series. Related parts include the DAC6571 (10-bit) and DAC5571 (8-bit), offering trade-offs between resolution, speed, and cost. The family shares similar interfaces and packaging options to facilitate scalable design transitions.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same package include the DAC7571IDBVR and DAC7571IDBVT. These variants share identical electrical characteristics and pinouts, differing primarily in packaging format such as cut tape versus reel. Verify that any replacement maintains the same temperature grade and RoHS compliance status.
