DAC7624U

Digital To Analog Converters Overview

The DAC7624U is a quad, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features four buffered voltage outputs and utilizes an R-2R resistor ladder architecture. The device operates with a single 5V supply and supports parallel data interfaces. Key electrical specifications include a settling time of 10 microseconds, a sampling rate of 100 kS/s, and a maximum power dissipation of 15 mW. Differential nonlinearity is specified at +/- 1 LSB, while integral nonlinearity is +/- 2 LSB. The component functions within a temperature range of -40°C to +85°C and is housed in a SOIC-28 surface-mount package.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with internal buffering for direct drive capability.
• Features a reset function that forces outputs to mid-scale upon power-up or system reset.
• Utilizes a low-power R-2R architecture designed for minimal energy consumption during operation.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Portable instrumentation utilizing single-supply operation
• Battery-powered test equipment needing low quiescent current

Digital To Analog Converters Procurement Notes

Verify the manufacturer designation on the datasheet, as National Semiconductor was acquired by Texas Instruments. Confirm the specific suffix 'U' corresponds to the SOIC-28 package variant. Ensure compliance with RoHS directives if required for the target assembly. Cross-reference the Mouser part number 595-DAC7624U for accurate sourcing details.

Digital To Analog Converters Selection Notes

Select this component when four isolated analog outputs are required from a single digital source. The 12-bit resolution balances precision with speed for general-purpose applications. Consider the parallel interface requirements against available microcontroller GPIO lines. Evaluate the 10-microsecond settling time against the system's update rate needs.

Digital To Analog Converters Part Context

This device belongs to the DAC7624 family of quad digital-to-analog converters. It shares architectural similarities with the DAC7625 but may differ in specific performance metrics or pin configurations. The series is designed for cost-sensitive applications requiring multiple output channels without external amplification.

Digital To Analog Converters Replacement Considerations

The DAC7625U is a documented alternative within the same product family. Verify functional compatibility regarding pinout and register mapping before substitution. Check datasheets for any differences in gain error or linearity specifications between the two variants.
