DAC5311IDCKRQ1

Digital To Analog Converters Overview

The DAC5311IDCKRQ1 is an automotive-grade, 8-bit, single-channel digital-to-analog converter (DAC) manufactured by Texas Instruments. It operates on a supply voltage range of 1.8V to 5.5V with a typical quiescent current of 80µA. The device features a 6-pin SC-70 package and supports serial interfaces including SPI, QSPI, Microwire, and DSP modes with clock rates up to 50MHz. It provides rail-to-rail buffered voltage output and includes power-on reset to zero scale. The component is qualified for automotive applications and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Monotonic design with high linearity to minimize code transitions
• Integrated rail-to-rail output buffer amplifier

Digital To Analog Converters Applications

• Portable battery-powered instruments
• Process control systems
• Programmable voltage and current sources
• Digital gain and offset adjustment circuits

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'Q1' confirms automotive grade status and the 'R' indicates tape-and-reel packaging. Confirm the operating temperature range matches the -40°C to +85°C specification required for your application environment. Ensure compatibility with the 1.8V minimum supply voltage if using lower voltage logic levels.

Digital To Analog Converters Selection Notes

Select this component when automotive certification is mandatory for an 8-bit resolution requirement. It serves as a direct pin-compatible upgrade from standard industrial grades if higher reliability is needed. Consider the 6-pin SC-70 footprint for space-constrained designs. Verify that the 80µA active current meets system power budgets compared to higher-performance but more power-hungry alternatives.

Digital To Analog Converters Part Context

This part belongs to the DACx311 family of low-power DACs. It shares pinout compatibility with other members like the DAC7311 and DAC8311, allowing for resolution upgrades without PCB redesign. The IDCKR variant specifically denotes the industrial/automotive temperature range and reel packaging format within the broader product line.

Digital To Analog Converters Replacement Considerations

The DAC5311IDCKT is a compatible alternative in cut-tape packaging. For higher resolution needs, the DAC7311IDCKR offers 12-bit performance with identical pinouts. Standard industrial versions like the DAC5311IDCKR may be used if automotive qualification is not strictly required.
