DAC7631EBG4

Digital To Analog Converters Overview

The DAC7631EBG4 is a single-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture to provide buffered voltage output with a range of ±2.5 V. The device operates on a single 5 V supply and features a serial interface for data input. Key performance metrics include a settling time of 10 µs, a sample rate of 93 kS/s, and low power consumption of 1.8 mW. Nonlinearity specifications are defined by a maximum integral nonlinearity (INL) of ±3 LSB and differential nonlinearity (DNL) of ±2 LSB. It is housed in a 20-pin SSOP package and supports an operating temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrated reset function allows the output to return to mid-scale upon power-up or command.
• Serial data output (SDO) pin enables daisy-chaining of multiple devices for system expansion.
• Buffered voltage output stage eliminates the need for external amplification in many applications.

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation.
• Programmable gain amplifier circuits for sensor signal conditioning.
• Battery-powered instrumentation benefiting from low power consumption.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BG4' against the official Texas Instruments datasheet to confirm it denotes the lead-free, RoHS-compliant variant within the standard SSOP-20 package. Ensure the ordering part number matches the exact tape-and-reel or tube packaging requirements for your assembly line. Cross-reference the manufacturer's latest documentation to confirm current availability and any potential lifecycle status changes.

Digital To Analog Converters Selection Notes

Select this component when a high-resolution 16-bit output is required with minimal external circuitry. The integrated buffer simplifies design compared to unbuffered counterparts. Consider the serial interface constraints if high-speed data throughput is critical, as the 93 kS/s update rate may limit application bandwidth. Verify that the ±2.5 V output swing aligns with the downstream analog input requirements.

Digital To Analog Converters Part Context

This device belongs to the DAC7631 family of serial input digital-to-analog converters. It shares architectural similarities with other members like the DAC7631E but may differ in packaging or environmental compliance based on the suffix. The family is designed for cost-sensitive, space-constrained applications where moderate speed and high resolution are balanced.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include DAC7631E and DAC7631EB/1KG4. Verify pin compatibility and electrical specifications before substitution. Other families such as DAC7311 offer different resolutions and interfaces and are not direct replacements.
