TLV5631IDWR

Digital To Analog Converters Overview

The TLV5631IDWR is a low-power, eight-channel digital-to-analog converter (DAC) manufactured by Texas Instruments. It features a resistor-string architecture with 10-bit resolution and supports serial interfaces including DSP, Microwire, QSPI, and SPI. The device operates on analog and digital supply voltages ranging from 2.7 V to 5.5 V. Key electrical specifications include a settling time of 1 µs, a sampling rate of 283 kS/s, and a typical operating current of 6 mA. Differential nonlinearity is specified at 1 LSB, while integral nonlinearity is 2 LSB. The gain error is limited to 0.6% FSR. It is housed in a TSSOP-20 package and is designed for industrial temperature ranges from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates eight independent voltage-output DAC channels within a single compact package.
• Supports multiple high-speed serial communication protocols for flexible microcontroller interfacing.
• Includes an internal reference option alongside external reference capability for system design flexibility.

Digital To Analog Converters Applications

• Programmable power supplies requiring multi-channel voltage adjustment
• Industrial process control systems utilizing serial bus architectures
• Data acquisition front-ends for signal conditioning

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'WR' indicates the reel packaging format when sourcing components. Confirm that the ordering part number matches the required TSSOP-20 package variant. Ensure compatibility with the intended serial interface protocol before finalizing procurement decisions.

Digital To Analog Converters Selection Notes

Select this component when eight simultaneous analog outputs are required without occupying excessive board space. Consider the 10-bit resolution and 283 kS/s update rate against application precision needs. Evaluate the 6 mA current consumption relative to total system power budgets.

Digital To Analog Converters Part Context

This device belongs to the TLV5631 family of low-power DACs. It shares architectural similarities with other members like the TLV5632 but offers higher resolution. The IDWR suffix denotes the industrial temperature range and tape-and-reel packaging, distinguishing it from tube-packaged variants.

Digital To Analog Converters Replacement Considerations

The TLV5631IPWR serves as a pin-compatible alternative with potentially different performance grades or packaging options. Verify electrical parameter equivalence before substitution.
