DAC7725UB/1K

Digital To Analog Converters Overview

The DAC7725UB/1K is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture to achieve a sampling rate of 100 kS/s with a settling time of 10 µs. The device features buffered voltage outputs and supports both bipolar and unipolar operation modes via an external reference. It operates on dual power supplies ranging from ±14.25 V to ±15.75 V for analog circuits and a separate 5 V supply for digital logic. Key performance metrics include a maximum integral nonlinearity (INL) of ±2 LSB and a differential nonlinearity (DNL) of ±1 LSB. The component is housed in a 28-pin 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 high drive capability.
• Supports flexible output polarity configurations for both bipolar and unipolar signal ranges.
• Includes a reset function that initializes all channels to mid-scale upon activation.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel precision voltage generation.
• Programmable gain amplifier stages in test and measurement instrumentation.
• Data acquisition front-ends utilizing parallel interface communication.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details. The '/1K' designation typically indicates reel packaging containing one thousand units per reel. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure the procurement source provides valid traceability data for quality assurance compliance.

Digital To Analog Converters Selection Notes

Select this component when a parallel interface is required for high-speed data throughput across multiple channels. Compare against the serial interface variant, DAC7715, if pin count reduction or simplified wiring is prioritized over raw bandwidth. Verify that the ±15 V supply rails are available in the target system design to meet the specified operating voltage requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC772x family of precision digital-to-analog converters. It shares architectural similarities with the DAC7724 but differs in specific linearity specifications and package options. The DAC7725 series is designed for applications demanding moderate speed and high accuracy in industrial environments.

Digital To Analog Converters Replacement Considerations

The DAC7725N serves as a leaded PLCC alternative within the same functional family. Check datasheets for pin compatibility and electrical parameter alignment before substitution.
