DAC7634EB/1K

Digital To Analog Converters Overview

The DAC7634EB/1K is a quad-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder architecture with serial input interfaces and buffered voltage outputs. The device operates on a single 5 V analog supply and a 5 V digital supply, supporting an update rate of 89 kS/s per channel. Key electrical specifications include a settling time of 10 µs, a differential nonlinearity (DNL) of ±2 LSB, and an integral nonlinearity (INL) of ±3 LSB. Gain error is specified at 0.08% FSR. It is housed in a 48-pin SSOP package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Four independent 16-bit channels providing simultaneous or sequential voltage output generation.
• Serial interface compatibility for efficient data transmission with reset-to-mid-scale capability.
• Integrated buffered outputs designed to drive external loads without requiring additional amplification.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation.
• Programmable power supplies and test equipment needing precise voltage references.
• Data acquisition systems utilizing high-resolution analog output stages.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'EB/1K' against official Texas Instruments documentation to confirm packaging configuration and material compliance. Ensure the ordering information matches the required tube quantity and RoHS status before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when four isolated 16-bit voltage outputs are required from a single IC. The serial interface reduces pin count compared to parallel alternatives. Verify that the 10 µs settling time meets system speed requirements and that the 5 V supply voltage aligns with the target application's power rails.

Digital To Analog Converters Part Context

This part belongs to the DAC7634 family of quad 16-bit DACs. It shares architectural similarities with the DAC7631 (single channel) and DAC7644 (parallel interface). The 'E' designation typically indicates lead-free and RoHS compliance, while '/1K' denotes the specific tube packaging quantity.

Digital To Analog Converters Replacement Considerations

For direct functional replacements, consider the DAC7644 if a parallel interface is acceptable. For serial interface needs, the DAC7734 offers similar performance but may require interface adaptation. Verify pinout compatibility before substitution.
