DAC7541AKU/1KG4

Digital To Analog Converters Overview

The DAC7541AKU/1KG4 is a low-cost, 12-bit CMOS four-quadrant multiplying digital-to-analog converter manufactured by Texas Instruments. It features laser-trimmed thin-film resistors on a monolithic CMOS circuit to provide true 12-bit integral and differential linearity over the full specified temperature range. The device operates with a single +5V to +16V supply and accepts TTL- or CMOS-compatible parallel digital inputs. It provides unbuffered current outputs (IOUT1 and IOUT2) and includes an internal feedback resistor for external op-amp configuration.

Digital To Analog Converters Feature Summary

• Direct pin-for-pin replacement for industry standard 7521, 7541, and 7541A parts
• Four-quadrant multiplication capability allowing AC or DC reference signals
• Monotonicity guaranteed over the full operating temperature range
• Latch-up resistant design with ESD protection on digital control inputs

Digital To Analog Converters Applications

• Digitally controlled gain blocks requiring variable amplification
• Unipolar binary operation for two-quadrant multiplication applications
• Bipolar four-quadrant multiplier circuits using external summing amplifiers

Digital To Analog Converters Procurement Notes

Verify that the specific ordering suffix matches the required package quantity and screening options. Confirm the manufacturer source is authorized to ensure component authenticity and traceability. Check for any burn-in screening requirements if high reliability is necessary for the application environment.

Digital To Analog Converters Selection Notes

Select this component when a direct upgrade from legacy 7521/7541 devices is needed without PCB layout changes. Ensure the output interface supports unbuffered current mode, as voltage output requires an external operational amplifier. Verify that the power supply range of +5V to +16V aligns with the system design constraints.

Digital To Analog Converters Part Context

This part belongs to the Burr-Brown DAC7541A family, originally developed by Burr-Brown Corporation and now produced by Texas Instruments. The series is designed as a cost-effective solution for general-purpose digital-to-analog conversion tasks requiring 12-bit resolution and multiplying capabilities in industrial and instrumentation environments.

Digital To Analog Converters Replacement Considerations

Public confirmed substitute part numbers include DAC7541AKP, DAC7541AJU, and DAC7541JP. These variants share identical electrical specifications and pinouts but differ in package type (Plastic DIP vs. Plastic SOIC) or accuracy grade.
