DAC7634EB

Digital To Analog Converters Overview

The DAC7634EB is a quad-channel, 16-bit voltage output digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor string architecture and operates with a serial interface. The device supports dual power supplies of ±5 V or a single +5 V supply. Key electrical specifications include a settling time of 10 µs, a sample rate of 89 kS/s, and a typical power consumption of 7.5 mW. Differential nonlinearity (DNL) is specified at ±2 LSB, while integral nonlinearity (INL) is ±3 LSB. The component 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

• Integrates four independent 16-bit DAC channels within a single compact package for space-constrained designs.
• Utilizes an R-2R resistor string architecture to deliver buffered voltage outputs with low power consumption.
• Includes a serial interface compatible with standard communication protocols for simplified system integration.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable gain amplifiers and variable voltage references
• Data acquisition systems needing precise analog output stages

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'E' confirms lead-free compliance and RoHS status as per manufacturer documentation. Confirm the 'B' suffix indicates tape-and-reel packaging if reel handling is required for assembly. Ensure the operating voltage ranges match the target application's power supply constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when four synchronized 16-bit outputs are necessary. Compare against the DAC7631E for single-channel needs or the DAC7634E for tube-packaged inventory requirements. Evaluate the 89 kS/s update rate against application bandwidth requirements to ensure sufficient performance margins.

Digital To Analog Converters Part Context

This part belongs to the DAC763x family of high-resolution digital-to-analog converters from Texas Instruments. It shares architectural similarities with the DAC7631 but expands channel count to four. The series is designed for general-purpose analog output applications requiring precision and low power.

Digital To Analog Converters Replacement Considerations

The DAC7634E serves as a direct functional equivalent differing primarily in packaging format. Verify pin compatibility and software register settings when substituting between tube and reel variants within the same family.
