DAC7625UB

Digital To Analog Converters Overview

The DAC7625UB is a quad 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor string architecture with buffered voltage outputs. The device operates on a single 5V digital supply and dual ±5V analog supplies, consuming 15 mW of power. It supports parallel data interfaces and achieves a sampling rate of 100 kS/s with a settling time of 10 µs. Non-linearity specifications include ±1 LSB for both DNL and INL, with a gain error of 0.2% FSR. The component is housed in a 28-SOIC package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with internal buffering for direct drive capability.
• Utilizes R-2R architecture to ensure high linearity and low differential/integral non-linearity errors.
• Supports standard parallel digital interfaces for straightforward integration with microcontrollers or DSPs.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable power supply designs needing precise voltage references
• Data acquisition front-ends for waveform generation

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'UB' corresponds to the 28-SOIC surface-mount package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure that the external voltage reference requirements align with the specified ±5V analog supply rails to maintain accuracy.

Digital To Analog Converters Selection Notes

Select this component for applications requiring four synchronized 12-bit outputs with moderate speed. Compare against the DAC7625U if tape-and-reel packaging is preferred over tubes. Consider the DAC7725 series if higher voltage operation (±15V) is required instead of the ±5V range provided here.

Digital To Analog Converters Part Context

This part belongs to the DAC7625 family of quad 12-bit DACs from Texas Instruments. It shares architectural similarities with the DAC7624 but differs in channel count. The UB suffix denotes the SOIC package option, distinct from other package variants like the DIP or PLCC options found in related model numbers.

Digital To Analog Converters Replacement Considerations

The DAC7625U serves as a pin-compatible alternative offering tube packaging instead of the specific UB variant configuration. For higher voltage applications, the DAC7725 provides similar functionality but requires ±15V supplies.
