TLV5638IDG4

Digital To Analog Converters Overview

The TLV5638IDG4 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 voltage-buffered outputs. The device operates on a single analog and digital power supply ranging from 2.7 V to 5.5 V. It supports multiple serial interface protocols including 3-Wire, DSP, Microwire, QSPI, and SPI. Key performance metrics include a settling time of 1 µs, a sampling rate of 233 kS/s, and a typical power consumption of 4.5 mW. Differential nonlinearity is specified at +/- 0.4 LSB, while integral nonlinearity is +/- 1.7 LSB. The component is housed in an SOIC-8 surface-mount package and is rated for operation between -40°C and +125°C.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'DG4' confirms the tube packaging format and lead-free compliance status required for your assembly process. Confirm that the SOIC-8 footprint matches your PCB layout constraints. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet revision to verify pinout consistency with existing designs.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution is required within a compact SOIC-8 package. It is suitable for applications needing moderate speed and high accuracy without the complexity of multi-chip solutions. Consider the TLV5638IDR variant if reel or cut-tape packaging is preferred over tubes for automated placement. Evaluate power budget requirements against the 4.5 mW consumption figure.

Digital To Analog Converters Part Context

This part belongs to the TLV5638 family of low-power DACs from Texas Instruments. It shares architectural similarities with other members like the TLV5639 but differs in channel count and package options. The IDG4 designation specifically identifies the industrial temperature grade version in an SOIC-8 tube. This series is designed to replace older, higher-power DACs in portable and space-constrained electronic designs.

Digital To Analog Converters Replacement Considerations

The TLV5638IDR serves as a functional equivalent with identical electrical characteristics but utilizes tape-and-reel packaging instead of tubes. Verify pin compatibility before substitution. No other direct cross-model replacements are confirmed in the provided documentation.
