DAC7634E

Digital To Analog Converters Overview

The DAC7634E is a quad, 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 for both analog and digital sections, with a maximum supply voltage of 5.25 V. Key electrical parameters include a sampling rate of 89 kS/s, a settling time of 10 µs, and a typical power consumption of 7.5 mW. Linearity specifications are defined by a differential nonlinearity (DNL) of ±2 LSB and an integral nonlinearity (INL) of ±3 LSB. The gain error is specified at 0.08% of full-scale range. 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

• Integrates four independent 16-bit DAC channels within a single compact package.
• Includes a reset function that forces outputs to mid-scale upon power-up.
• Features a serial data output (SDO) pin for daisy-chaining multiple devices.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable logic controller (PLC) analog output modules
• Test and measurement equipment calibration sources

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with system voltage levels and serial communication protocols before integration. Check for moisture sensitivity level requirements during storage and handling procedures.

Digital To Analog Converters Selection Notes

Select this component when four isolated 16-bit voltage outputs are required from a single serial bus. Compare settling time and linearity specifications against application tolerance requirements. Consider the SSOP-48 footprint constraints relative to available PCB real estate and thermal dissipation needs.

Digital To Analog Converters Part Context

This part belongs to the DAC763x family of low-power, high-resolution digital-to-analog converters. It shares architectural similarities with the single-channel DAC7631E but provides four times the channel density. The series is designed for applications demanding precise analog signal generation with minimal external component count.

Digital To Analog Converters Replacement Considerations

The DAC7634EP is a pin-compatible alternative offering the same functionality in a plastic SOIC-48 package instead of the SSOP variant. Verify package dimensions and thermal characteristics if substituting into existing footprints.
