DAC5571IDBVR

Digital To Analog Converters Overview

The DAC5571IDBVR is a single-channel, 8-bit digital-to-analog converter manufactured by Texas Instruments. It features a resistor-string architecture with an integrated buffered voltage output capable of rail-to-rail swing from 0 V to VDD. The device operates on a supply voltage range of 2.7 V to 5.5 V for both analog and digital domains. Key electrical parameters include a maximum settling time of 8 µs, a sampling rate of 188 kS/s, and a typical operating current of 155 µA at 3 V. Non-linearity specifications are ±0.5 LSB INL and ±0.25 LSB DNL maximum. It utilizes an I2C-compatible serial interface with clock rates up to 3.4 Mbps and functions within a temperature range of -40°C to +105°C in a SOT-23-6 package.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as tape and reel or cut tape, as these affect handling but not function. Confirm RoHS compliance status and moisture sensitivity level requirements against assembly process capabilities. Ensure the supplier provides valid traceability documentation for the Texas Instruments manufacturer part number.

Digital To Analog Converters Selection Notes

Select this component when a low-pin-count, cost-effective solution is required for applications needing moderate resolution and speed. The SOT-23-6 package is suitable for space-constrained designs. Consider the 8-bit resolution and 188 kSps update rate against system accuracy and bandwidth requirements before choosing higher-resolution family members like the DAC6571 or DAC7571.

Digital To Analog Converters Part Context

This part belongs to the DAC5571 family of low-power, single-channel I2C DACs. It shares architectural similarities with the DAC6571 (10-bit) and DAC7571 (12-bit), offering a scalable platform for designers requiring different resolution levels. The IDBVR suffix specifically denotes the industrial temperature grade and SOT-23-6 surface-mount packaging configuration.

Digital To Analog Converters Replacement Considerations

The DAC5571IDBVRG4 is a verified equivalent part number representing the same functional device with Green/RoHS-compliant manufacturing attributes. Other family members like DAC6571IDBVR offer higher resolution but maintain pin compatibility.
