DAC7541AJP

Digital To Analog Converters Overview

The DAC7541AJP is a low-cost, 12-bit CMOS four-quadrant multiplying digital-to-analog converter manufactured by Burr-Brown. It utilizes laser-trimmed thin-film resistors on a monolithic CMOS circuit to ensure true 12-bit integral and differential linearity across the full specified temperature range. The device operates with parallel binary word input and supports analog supply voltages ranging from 5 V to 16 V. It features an end-point linearity of ±1/2 LSB maximum over temperature. The component is housed in an 18-pin plastic DIP package and serves as a direct pin-for-pin replacement for industry standard parts such as the 7521, 7541, and 7541A.

Digital To Analog Converters Feature Summary

• Four-quadrant multiplying capability allows the analog output to be proportional to both the digital input code and the external reference voltage.
• Monolithic CMOS construction with laser-trimmed thin-film resistors provides high precision without requiring external trimming components.
• Direct pin-compatible replacement for legacy industry standard DACs, facilitating easy upgrades to existing designs.

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation
• Programmable gain amplifiers and variable gain stages
• Waveform generation circuits for test and measurement equipment

Digital To Analog Converters Procurement Notes

Verify the manufacturer origin, as the part was originally a Burr-Brown product now integrated into Texas Instruments' portfolio. Confirm the specific suffix 'JP' corresponds to the 18-pin plastic DIP package variant. Ensure the revision level matches the design requirements for linearity and operating temperature specifications.

Digital To Analog Converters Selection Notes

Select this component when a cost-effective, single-channel 12-bit resolution is required for applications needing four-quadrant multiplication. It is suitable for designs already utilizing legacy 7521 or 7541 footprints that require modern CMOS reliability. Consider the parallel interface requirement and the need for an external reference voltage source for operation.

Digital To Analog Converters Part Context

The DAC7541A belongs to the broader family of multiplying DACs derived from the classic 7521 architecture. This lineage ensures broad compatibility with older industrial standards while offering improved CMOS performance characteristics. The device represents a transition point where traditional bipolar DAC functions were adapted to more efficient CMOS processes.

Digital To Analog Converters Replacement Considerations

The datasheet explicitly identifies the DAC7541A as a direct, improved pin-for-pin replacement for the 7521, 7541, and 7541A industry standard parts. Designers can substitute these legacy components without modifying the PCB footprint or basic circuit topology.
