DAC7562TDGST

Digital To Analog Converters Overview

The DAC7562TDGST is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates within an analog and digital supply voltage range of 2.7 V to 5.5 V. The device features a string architecture with buffered voltage outputs and supports multiple serial interfaces including SPI, Microwire, QSPI, DSP, and 3-Wire. Key performance metrics include a settling time of 10 µs, a sampling rate of 100 kS/s, and a typical operating current of 900 µA. Nonlinearity specifications are defined by a maximum integral nonlinearity (INL) of ±0.3 LSB and differential nonlinearity (DNL) of ±0.05 LSB. It is housed in a 10-lead MSOP package and functions across a temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Supports flexible digital interface compatibility with standard SPI, Microwire, QSPI, DSP, and 3-Wire protocols.
• Provides low power consumption suitable for battery-operated applications with minimal active current draw.
• Delivers high accuracy through tight integral and differential nonlinearity specifications.

Digital To Analog Converters Applications

• Portable instrumentation systems requiring low power and small form factor.
• Battery-powered measurement devices utilizing the wide supply voltage range.
• Industrial process control loops needing precise analog signal generation.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'T' indicates the extended industrial temperature range (-40°C to +125°C) compared to standard variants. Confirm the 'DGST' suffix corresponds to the MSOP-10 package type and tape-and-reel shipping configuration. Ensure compatibility with system voltage levels matches the 2.7 V to 5.5 V operational limits before integration.

Digital To Analog Converters Selection Notes

Select this component when dual-channel output is required alongside strict linearity constraints. Compare against the DAC7562SDGST if lower power consumption is prioritized over the extended temperature range. Consider the DAC7562TDSCT if a WSON-10 footprint is preferred for space-constrained designs while maintaining similar electrical characteristics.

Digital To Analog Converters Part Context

This part belongs to the DAC7562T series, which focuses on low-power, 12-bit dual DAC solutions. It shares architectural similarities with the DAC7562 and DAC7563 families but distinguishes itself through its specific temperature rating and interface flexibility. It serves as a bridge between higher precision 16-bit converters and simpler 8-bit or 10-bit alternatives.

Digital To Analog Converters Replacement Considerations

DAC7562SDGST: Similar electrical specs but typically rated for commercial temperature ranges; verify thermal requirements. DAC7562TDSCT: Identical electrical performance but utilizes a WSON-10 package instead of MSOP-10, requiring PCB layout adjustments.
