DAC0832LCWM

Digital To Analog Converters Overview

The DAC0832LCWM is an 8-bit microprocessor-compatible, double-buffered digital-to-analog converter manufactured by Texas Instruments. It utilizes a CMOS/Si-Cr architecture with an R-2R resistor ladder network to provide current outputs proportional to the digital input and reference voltage. The device operates on a single power supply ranging from 5 VDC to 15 VDC and features TTL-compatible logic inputs. It supports 4-quadrant multiplication and includes an internal feedback resistor for external operational amplifier configurations.

Digital To Analog Converters Feature Summary

• Double-buffered digital data inputs allow simultaneous updating of multiple converters in a system.
• Pin-compatible with the 12-bit DAC1230 series for easy resolution upgrades without hardware changes.
• Direct interface capability with popular microprocessors including 8080, 8048, 8085, and Z80.
• Low power dissipation design suitable for battery-operated or thermally constrained applications.

Digital To Analog Converters Applications

• Microprocessor-based industrial control systems requiring analog output generation.
• Programmable gain amplifiers and variable voltage/current sources.
• Waveform generation circuits utilizing function generators or ROM-driven data streams.
• Digital potentiometer replacements in calibration and trimming applications.

Digital To Analog Converters Procurement Notes

Verify the specific suffix LCWM confirms the SOIC-20 surface mount package and the 0°C to +70°C commercial operating temperature range. Confirm RoHS compliance status as original datasheets may list non-compliant variants. Ensure the source document matches the SNAS534B revision for accurate electrical limits.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution with double buffering is required for direct microprocessor interfacing. Consider the DAC1230 if higher 12-bit resolution is needed while maintaining pin compatibility. Evaluate the need for external op-amps for voltage conversion, as the device provides current outputs only. Verify that the system's digital logic levels align with the specified TTL thresholds.

Digital To Analog Converters Part Context

The DAC0832 belongs to the MICRO-DAC family of multiplying digital-to-analog converters. It serves as the 8-bit counterpart to the 12-bit DAC1230, sharing similar architectural features and control signals. This lineage allows for scalable system designs where resolution can be increased by swapping components without altering the board layout or software addressing schemes.

Digital To Analog Converters Replacement Considerations

The DAC0832LCN/NOPB offers a PDIP through-hole alternative with identical electrical specifications. For lead-free and RoHS-compliant versions within the same package, verify availability of the DAC0832LCWM/NOPB variant. Cross-reference with the DAC1230 series if 12-bit resolution is acceptable for the application requirements.
