DAC7634E/1K

Digital To Analog Converters Overview

The DAC7634E/1K is a quad-channel, 16-bit voltage output digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor string architecture with a serial interface and operates on a single 5 V supply. The device provides four independent analog outputs with a settling time of 10 µs and a sampling rate of 89 kS/s per channel. Key electrical specifications include a differential nonlinearity (DNL) of ±2 LSB and integral nonlinearity (INL) of ±3 LSB. It functions within a temperature range of -40°C to +85°C and is housed in a 48-pin SSOP package.

Digital To Analog Converters Feature Summary

• Integrates four independent 16-bit DAC channels for multi-axis control applications
• Supports serial communication interfaces for simplified microcontroller connectivity
• Includes internal reset functionality to mid-scale upon power-up or command
• Delivers buffered voltage outputs suitable for driving external loads directly

Digital To Analog Converters Applications

• Industrial process control systems requiring multiple analog setpoints
• Multi-axis motion control drives and servo amplifiers
• Programmable power supply voltage references
• Test and measurement equipment signal generation

Digital To Analog Converters Procurement Notes

Verify the specific suffix '1K' indicates reel packaging rather than tube packaging when reviewing distributor listings. Confirm RoHS compliance status through official datasheets as manufacturing revisions may vary. Ensure the SSOP-48 footprint matches the target PCB design constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when four synchronized 16-bit voltage outputs are required from a single IC. Compare against the DAC7634E if reel packaging is not necessary. Consider the DAC7631E for single-channel applications to reduce cost and board space. Verify that the 89 kS/s update rate meets the system bandwidth requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC763x family of low-power, 16-bit digital-to-analog converters. It shares architectural similarities with the DAC7631 (single channel) and DAC7632 (dual channel). The series is designed for general-purpose analog output applications where moderate speed and high resolution are balanced with low power consumption.

Digital To Analog Converters Replacement Considerations

Public confirmed substitutes include DAC7634E for tube-packaged equivalents. For reel-packaged alternatives, verify availability of DAC7634E/1K from other authorized distributors. Cross-reference with DAC7644 for similar quad-channel performance but different interface characteristics.
