DAC7541AKU

Digital To Analog Converters Overview

The DAC7541AKU 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 features an end-point linearity of ±1/2 LSB maximum over temperature. It is housed in a green plastic SOIC-18 package (JESD-30 code R-PDSO-G18) with 18 terminals. The component serves as a direct pin-for-pin replacement for industry standard parts including the 7521, 7541, and 7541A.

Digital To Analog Converters Feature Summary

• Four-quadrant multiplying capability allowing analog output proportional to both digital input and reference voltage
• Laser-trimmed thin-film resistor architecture ensures high precision linearity without external adjustment
• Direct pin-compatible replacement for legacy 7521, 7541, and 7541A components

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation
• Programmable gain amplifier circuits utilizing multiplying functionality
• Waveform generation applications where cost-effective 12-bit resolution is required

Digital To Analog Converters Procurement Notes

Verify the manufacturer designation as Burr-Brown when sourcing this component. Confirm the suffix 'KU' corresponds to the 18-pin plastic SOIC package variant. Ensure compatibility with existing designs referencing the 7541A standard, noting that while functionally equivalent, specific electrical tolerances should be cross-referenced against the original datasheet requirements for critical applications.

Digital To Analog Converters Selection Notes

Select the DAC7541AKU when a cost-sensitive solution is needed for 12-bit digital-to-analog conversion with multiplying capabilities. It is suitable for designs currently using 7521 or 7541 parts that require an upgrade to CMOS technology for improved power characteristics. The parallel interface requirement must be accommodated in the system design, as serial interfaces are not supported by this specific model.

Digital To Analog Converters Part Context

This component belongs to the Burr-Brown family of low-cost digital-to-analog converters. It is specifically designed to replace older bipolar or hybrid DAC standards like the 7521 and 7541. The 'A' designation typically indicates improved specifications such as tighter linearity bounds compared to earlier iterations, while the 'KU' suffix identifies the surface-mount SOIC packaging option.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitute part numbers include the 7521, 7541, and 7541A. These devices are documented as industry standards directly replaced by the DAC7541A series. Verify pinout compatibility before substitution, although the DAC7541A is explicitly described as a direct pin-for-pin replacement.
