DAC7724U/1K

Digital To Analog Converters Overview

The DAC7724U/1K is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor string architecture with buffered voltage outputs and a parallel interface. The device operates on dual analog supply voltages of ±15 V and a 5 V digital supply. Key performance metrics include a sampling rate of 100 kS/s, a settling time of 10 µs, and a power consumption of 45 mW. Linearity specifications are defined by 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 supports an operating temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit converters within a single compact package for multi-channel signal generation.
• Provides buffered voltage outputs to drive external loads without requiring additional amplification stages.
• Includes a reset function that initializes all channels to mid-scale output levels upon activation.

Digital To Analog Converters Applications

• Industrial process control systems requiring precise multi-axis positioning or valve actuation.
• Data acquisition equipment needing simultaneous analog signal generation across multiple channels.
• Test and measurement instruments utilizing high-resolution waveform synthesis.

Digital To Analog Converters Procurement Notes

Verify the specific suffix '1K' against the manufacturer's official documentation to confirm packaging details, as standard datasheets may reference tube packaging for the base DAC7724U model. Ensure compatibility with the required 28-pin SOIC footprint and validate that the parallel interface logic levels match the host system's digital supply voltage.

Digital To Analog Converters Selection Notes

Select this component when a design requires four synchronized 12-bit outputs with low settling times. The parallel interface necessitates more GPIO pins compared to serial alternatives like the DAC7715. Consider the ±15 V supply requirement, which differs from single-supply devices, and ensure the PCB layout accommodates the thermal dissipation characteristics of the SOIC-28 package under continuous operation.

Digital To Analog Converters Part Context

This part belongs to the DAC7724 family of precision data converters. It shares architectural similarities with the DAC7624 but utilizes higher voltage supplies suitable for industrial environments. The DAC7724N variant offers a PLCC package option, while the U suffix denotes the SOIC surface-mount configuration. These devices serve as direct replacements for older legacy quad-channel DACs in established industrial designs.

Digital To Analog Converters Replacement Considerations

The DAC7724N serves as a pin-compatible alternative offering a PLCC package instead of SOIC. For designs requiring serial communication, the DAC7715UB provides similar resolution and channel count with reduced pin requirements. Verify that any substitute maintains the same ±15 V supply capability and parallel interface timing constraints.
