TLV5638IDR

Digital To Analog Converters Overview

The TLV5638IDR is a dual-channel, low-power digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a 12-bit resolution and utilizes a resistor-string architecture to provide buffered voltage outputs. The device operates within a supply voltage range of 2.7 V to 5.5 V and consumes only 4.5 mW of power. It supports multiple serial interface protocols including SPI, Microwire, QSPI, DSP, and 3-Wire modes. The component is housed in an 8-pin SOIC package and is rated for operation across an extended temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual-channel output capability with independent control
• Low power consumption suitable for battery-operated systems
• Flexible serial interface compatibility with standard communication protocols
• Extended industrial temperature rating for harsh environments

Digital To Analog Converters Applications

• Portable instrumentation requiring low power analog signal generation

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'IDR' corresponds to the SOIC-8 package and tape-and-reel packaging configuration. Confirm that the operating temperature range meets the application requirements, as the 'I' grade supports up to +125°C. Ensure the serial interface timing parameters align with the host microcontroller's clock speeds before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel DAC with 12-bit resolution is required in a compact surface-mount package. Consider the TLV5638 series if low power dissipation is critical compared to higher-speed alternatives. Verify that the input voltage levels are compatible with the digital logic family used in the system design.

Digital To Analog Converters Part Context

This part belongs to the TLV5638 family of low-power DACs from Texas Instruments. The family includes variants such as the TLV5638ID and TLV5638IP, which differ primarily in package type and temperature rating. The IDR suffix specifically denotes the industrial temperature grade and SOIC-8 surface-mount packaging format.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same family include the TLV5638ID and TLV5638IP. Verify that substitute parts maintain the same 12-bit resolution and serial interface compatibility. Check datasheets for any differences in settling time or gain error specifications.
