DAC7631E

Digital To Analog Converters Overview

The DAC7631E is a single-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture to provide voltage output with a sampling rate of 93 kS/s and a settling time of 10 µs. The device operates on a single 5 V supply, consuming approximately 1.8 mW of power. It features a serial interface for data input and includes specific functional capabilities such as reset to mid-scale and a serial data output (SDO) pin. The component is housed in a 20-pin SSOP package and is rated for operation within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates a serial interface for simplified microcontroller connectivity

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature rating. Ensure that any suffix variations do not alter the electrical characteristics or pinout configuration defined in the datasheet. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and current production status before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a high-resolution 16-bit output is required alongside low power consumption. The R-2R architecture offers a balance between speed and accuracy suitable for general-purpose applications. Consider the 10 µs settling time and 93 kS/s update rate to ensure compatibility with system timing requirements. Verify that the single-supply operation aligns with the available power rails in the target design.

Digital To Analog Converters Part Context

This device belongs to the DAC7631 family of digital-to-analog converters from Texas Instruments. The family focuses on providing high-resolution conversion with serial communication interfaces. Variations within the series may differ in packaging options or specific feature sets, but they share the core 16-bit resolution and R-2R architectural foundation designed for efficient analog signal processing.

Digital To Analog Converters Replacement Considerations
