DAC7725NB/750

Digital To Analog Converters Overview

The DAC7725NB/750 is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture to provide buffered voltage outputs with a settling time of 10 microseconds and a sampling rate of 100 kS/s per channel. The device operates on dual analog supply voltages ranging from ±14.25 V to ±15.75 V and a separate 5 V digital supply. It features parallel data interfaces and external voltage reference inputs. Non-linearity specifications include a maximum integral non-linearity (INL) of ±2 LSB and differential non-linearity (DNL) of ±1 LSB. The component is housed in a 28-pin PLCC package and supports an industrial operating temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Four independent 12-bit channels providing simultaneous buffered voltage outputs
• High-speed conversion capability with 10 microsecond settling time
• Robust linearity performance ensuring accurate signal reproduction
• Flexible power supply configuration supporting standard dual-rail analog and single-rail digital logic

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-axis regulation
• Programmable power supplies and test equipment
• Data acquisition systems with multiple analog output channels

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'NB/750' against official Texas Instruments documentation, as standard listings typically identify this family as DAC7725N or DAC7725NG4. Confirm current production status, as the base DAC7725 series has been marked for obsolescence in public records. Ensure compatibility with existing board layouts for the 28-PLCC footprint before procurement.

Digital To Analog Converters Selection Notes

Select this component when a design requires four synchronized analog outputs with moderate speed and high resolution. The parallel interface necessitates sufficient GPIO availability on the controlling microcontroller or FPGA. Consider the thermal dissipation characteristics of the PLCC package if operating at the upper limits of the specified temperature range.

Digital To Analog Converters Part Context

This part belongs to the DAC7725 family of precision digital-to-analog converters. It shares architectural similarities with the DAC7724 but offers four channels instead of two. The device is designed for applications demanding precise analog signal generation from digital inputs, serving as a bridge between digital control logic and analog actuators or sensors.

Digital To Analog Converters Replacement Considerations

Publicly documented substitutes within the same manufacturer portfolio include the DAC7724 for dual-channel requirements or the DAC7721 for single-channel configurations. Cross-referencing with newer generations such as the DAC7760 series may offer improved performance metrics and updated packaging options.
