DAC7724N/750

Digital To Analog Converters Overview

The DAC7724N/750 is a 12-bit quad voltage output digital-to-analog converter manufactured by Texas Instruments. It features four independent channels with an R-2R resistor string architecture, providing buffered voltage outputs. The device operates on dual analog supply voltages ranging from ±14.25 V to ±15.75 V and a single digital supply of 5 V. Key performance metrics include a settling time of 10 µs, a sampling rate of 100 kS/s per channel, and low non-linearity errors of ±1 LSB for both DNL and INL. It utilizes a parallel interface for data input and is housed in a 28-pin PLCC package.

Digital To Analog Converters Feature Summary

• Four independent 12-bit channels with buffered voltage outputs
• R-2R resistor string architecture for stable conversion
• Parallel digital interface for high-speed data transfer
• Reset to mid-scale functionality for safe power-up states

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable power supplies and test equipment
• Data acquisition systems with analog output capabilities

Digital To Analog Converters Procurement Notes

Verify the specific suffix /750 against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications, as military or extended temperature variants may differ from standard commercial grades. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements for your assembly process. Check for obsolescence notices or last-time buy notifications from Texas Instruments before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel, 12-bit resolution DAC with a parallel interface is required. Ensure the system design supports dual analog supplies up to ±15.75 V and a 5 V digital logic level. Compare the ±1 LSB linearity and 10 µs settling time against application requirements. Consider the PLCC-28 package constraints for PCB layout if surface mount space is limited.

Digital To Analog Converters Part Context

The DAC7724N/750 belongs to the DAC7724 family of precision digital-to-analog converters. It shares architectural similarities with the DAC7725 but differs in integral non-linearity specifications. This part is designed for applications demanding multiple synchronized analog outputs with high accuracy. It serves as a legacy solution in industrial automation where parallel interfaces are preferred over serial alternatives like SPI.

Digital To Analog Converters Replacement Considerations

The DAC7724UB and DAC7724N are functional equivalents within the same family, differing primarily in packaging (SOIC vs. PLCC). Verify that the replacement package fits the existing footprint or allows for reflow profile adjustments. Ensure the substitute part maintains the same ±1 LSB INL/DNL specifications and parallel interface timing requirements.
