DAC7311IDCKT

Digital To Analog Converters Overview

The DAC7311IDCKT 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 and operates on a 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards. The device supports analog and digital supply voltages ranging from 2V to 5.5V. Key electrical specifications include a typical settling time of 6µs, a sample rate of 83 kS/s, and a maximum integral nonlinearity (INL) of ±1 LSB. It functions within an industrial temperature range of -40°C to +125°C and is housed in a compact SC-70-6 surface-mount package.

Digital To Analog Converters Feature Summary

• Ultra-low power consumption suitable for battery-operated portable applications
• Monotonic design ensures stability and reduces code-transition glitches
• Integrated power-on reset circuit maintains output at 0V until valid data is written
• Pin-compatible upgrade path across the DACx311 family for varying resolution needs

Digital To Analog Converters Applications

• Battery-powered portable instrumentation
• Programmable gain amplifiers and variable voltage references
• Industrial process control systems requiring low power
• Data acquisition systems with limited space constraints

Digital To Analog Converters Procurement Notes

Verify the specific suffix IDCKT indicates the tape-and-reel packaging format distinct from cut-tape or tray options. Confirm the operating temperature grade matches the -40°C to +125°C specification required for your environment. Ensure the SC-70-6 footprint aligns with your PCB layout guidelines before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution is required alongside minimal power usage in a small form factor. Compare against DAC5311 or DAC6311 if lower resolution suffices, or DAC8311/DAC8411 for higher precision needs. Verify that the 2V to 5.5V supply range accommodates your system's voltage rails and that the serial interface timing meets your processor's clock requirements.

Digital To Analog Converters Part Context

This part belongs to the DACx311 series, which offers pin-compatible devices ranging from 8-bit to 16-bit resolutions. The series shares identical physical footprints and interface protocols, allowing designers to scale performance without redesigning the hardware. The DAC7311 specifically targets applications needing 12-bit accuracy with ultra-low quiescent current.

Digital To Analog Converters Replacement Considerations

DAC7311IDCKR: Identical electrical specifications; differs only in reel packaging quantity. DAC7311IDCKT: Same model identifier; verify supplier lot consistency. DAC8311IDCKT: Pin-compatible 14-bit version offering higher resolution. DAC6311IDCKT: Pin-compatible 10-bit version for cost-sensitive applications.
