TLV5639IDWR

Digital To Analog Converters Overview

The TLV5639IDWR is a low-power, single-channel 12-bit digital-to-analog converter (DAC) manufactured by Texas Instruments. It operates on a supply voltage range of 2.7 V to 5.5 V for both analog and digital domains. The device features a resistor-string architecture with an internal reference, delivering a buffered voltage output. Key performance metrics include a settling time of 3.5 µs, a sampling rate of 286 kS/s, and a power consumption of 2.7 mW. Linearity specifications are defined by a differential nonlinearity (DNL) of ±0.3 LSB and an integral nonlinearity (INL) of ±1.2 LSB. It is housed in an 8-pin SOIC package.

Digital To Analog Converters Feature Summary

• Integrates an internal reference source to simplify circuit design
• Provides a buffered voltage output for direct driving capabilities
• Supports serial interface communication protocols including SPI and Microwire

Digital To Analog Converters Applications

• Battery-powered instrumentation systems
• Portable medical devices requiring low power consumption
• Process control loops with single-channel requirements

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when ordering. Confirm that the operating temperature range aligns with industrial standards if deployed in extreme environments. Ensure the serial interface timing parameters match the host microcontroller's clock speeds to prevent data transmission errors during integration.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is sufficient for the application. Compare against the TLV5638 series if dual-channel functionality is required instead. Consider the internal reference feature to reduce external component count compared to devices requiring external references. Evaluate power constraints as the 2.7 mW consumption suits battery-operated designs.

Digital To Analog Converters Part Context

This part belongs to the TLV563x family of low-power DACs from Texas Instruments. It shares architectural similarities with the TLV5639IDW but differs in packaging format. The IDWR suffix specifically denotes the SOIC-8 surface-mount package supplied in reel form, distinguishing it from tube-packaged variants within the same electrical specification set.
