DAC0832LCWMX

Digital To Analog Converters Overview

The DAC0832LCWMX is an 8-bit multiplying digital-to-analog converter manufactured by Texas Instruments. It features a silicon-chromium R-2R resistor ladder network and operates with a single power supply ranging from 5 VDC to 15 VDC. The device utilizes double-buffered, single-buffered, or flow-through digital data inputs for flexible microprocessor interfacing. It provides current outputs (IOUT1 and IOUT2) that are proportional to the reference voltage and digital input code. The component supports full four-quadrant multiplication and includes internal feedback resistance for external operational amplifier configurations.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the specific suffix LCWM against the datasheet to confirm the operating temperature range of 0°C to +70°C. Ensure the package type matches the SOIC-20 physical dimensions specified in the connection diagrams. Confirm RoHS compliance status through official manufacturer documentation prior to integration into production designs.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution with high linearity accuracy is required for microprocessor interfaces. The double-buffered design is essential for systems needing synchronized updates across multiple channels. Consider the 1 µs settling time and low power dissipation of 20 mW for performance-constrained applications.

Digital To Analog Converters Part Context

This part belongs to the DAC0830 series, which are advanced CMOS/Si-Cr 8-bit multiplying DACs designed for direct microprocessor interfacing. The series includes variants like the DAC0830 and DAC0832, distinguished primarily by their linearity error specifications. The LCWM suffix indicates a plastic surface-mount package suitable for standard industrial temperature ranges.

Digital To Analog Converters Replacement Considerations

The DAC1230 is pin-compatible with one exception and offers 12-bit resolution. Substitution requires tying address bit A0 to the ILE pin to enable two-byte write instructions for seamless hardware and software migration without circuit modifications.
