DAC7571IDBVR

Digital To Analog Converters Overview

The DAC7571IDBVR is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an I2C receive-only interface and operates on analog and digital supply voltages ranging from 2.7 V to 5.5 V. The device utilizes a resistor-string architecture with a buffered voltage output capable of rail-to-rail swing. 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. Power dissipation is rated at 850 µW. Nonlinearity performance includes a differential nonlinearity (DNL) of ±1 LSB and integral nonlinearity (INL) of ±0.195 LSB. The component is housed in a SOT-23-6 package and supports an industrial temperature range from -40°C to +105°C.

Digital To Analog Converters Feature Summary

• Integrated buffered voltage output amplifier enabling rail-to-rail output swing capability
• I2C-compatible two-wire serial interface designed for receive-only operation
• Built-in power-on-reset circuit ensuring output initialization to zero volts upon power-up

Digital To Analog Converters Applications

• Battery-powered portable instrumentation systems requiring low power consumption
• Industrial process control loops utilizing I2C communication buses
• Data acquisition systems needing single-channel voltage generation

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the ordering part number matches the required temperature grade and package variant to avoid functional discrepancies during integration.

Digital To Analog Converters Selection Notes

Select this component for applications requiring 12-bit resolution with minimal pin count. Compare against the DAC6571 for 10-bit needs or DAC5571 for 8-bit requirements within the same family. Consider the DAC7574 if multiple channels are necessary. Verify that the I2C address configuration meets system bus constraints before finalizing the design.

Digital To Analog Converters Part Context

This part belongs to the DAC7571 series of low-power, cost-optimized digital-to-analog converters. It shares architectural similarities with the DAC6571 and DAC5571, differing primarily in resolution. The series is designed for space-constrained designs using the SOT-23-6 package. Evaluation modules such as the DAC7571EVM are available for development purposes.

Digital To Analog Converters Replacement Considerations

The DAC7571IDBVT serves as a tape-and-reel alternative with identical electrical characteristics. For lower resolution needs, the DAC6571IDBVR (10-bit) and DAC5571IDBVR (8-bit) are compatible pin-for-pin replacements within the same package.
