DAC7545GLUR

Digital To Analog Converters Overview

The DAC7545GLUR is a CMOS, 12-bit multiplying digital-to-analog converter manufactured by Texas Instruments. It features a single-channel current output and parallel interface within an SO-20 package. The device operates on a single +5V to +15V supply with a typical power dissipation of less than 0.5mW at 5V. Key electrical specifications include a gain error of ±0.5 LSB, differential nonlinearity of ±1 LSB, and a settling time of 2µs to 1/2 LSB. It ensures monotonicity over the commercial temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific GL grade accuracy class matches design requirements. Check for RoHS compliance status relevant to the manufacturing date code. Ensure proper ESD handling procedures are followed during storage and assembly to prevent latent damage to the CMOS input structures.

Digital To Analog Converters Selection Notes

Select this part when 12-bit resolution and four-quadrant multiplying functionality are required in a compact surface-mount package. The GL grade offers superior accuracy compared to standard grades, making it suitable for precision applications. Consider the parallel interface requirement and verify that the system timing meets the specified setup and hold times for reliable data latching.

Digital To Analog Converters Part Context

This component belongs to the DAC7545 family of multiplying DACs from Texas Instruments. It serves as a direct replacement for legacy parts like the AD7545 and PM-7545. The GLU variant denotes the active production version in the SOIC package, while the GLUR suffix indicates tape-and-reel packaging for automated assembly processes.

Digital To Analog Converters Replacement Considerations

The datasheet explicitly lists the AD7545 and PM-7545 as direct replacements. Verify pin compatibility and electrical parameter alignment before substitution. Note that other variants in the DAC7545 series may have different accuracy grades or packaging options.
