DAC7624UB

Digital To Analog Converters Overview

The DAC7624UB 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 sampling rate of 100 kS/s and achieves a settling time of 10 µs. It supports parallel data interfaces and requires analog supply voltages of ±5 V and a digital supply of 5 V. Key performance metrics include a differential nonlinearity (DNL) of ±1 LSB, integral nonlinearity (INL) of ±2 LSB, and a gain error of 0.2% FSR. Power consumption is rated at 15 mW, and the component functions within a temperature range of -40°C to +85°C in a 28-pin SOIC package.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with internal buffering for direct drive capability.
• Incorporates a reset function that forces all outputs to mid-scale upon power-up or command activation.
• Utilizes a parallel interface for high-speed data loading compatible with standard microprocessor buses.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'U' indicates the SOIC-28 surface-mount package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification. Cross-reference the full part number against current datasheets to validate pinout compatibility with existing PCB layouts.

Digital To Analog Converters Selection Notes

Select this component when four isolated 12-bit voltage outputs are required with moderate precision. The ±5 V analog supply requirement distinguishes it from single-supply alternatives. Consider the 10 µs settling time for bandwidth limitations in dynamic applications. Evaluate the parallel interface complexity against serial options if pin count is constrained.

Digital To Analog Converters Part Context

This unit belongs to the DAC762x family of quad DACs from Texas Instruments. It shares architectural similarities with the DAC7625 but differs in linearity specifications, specifically exhibiting higher INL values. The series provides a cost-effective solution for general-purpose analog output applications where extreme precision is not critical.

Digital To Analog Converters Replacement Considerations

The DAC7625UB serves as a functional substitute with improved INL performance (+/- 1 LSB). Verify interface compatibility and thermal characteristics before substitution.
