LTC7543GKSW#TRPBF

Digital To Analog Converters Overview

The LTC7543GKSW#TRPBF is a serial-input, 12-bit multiplying digital-to-analog converter (DAC) in a 16-lead plastic SO package. It serves as a direct replacement for the AD7543 and DAC-8143 with improved accuracy and stability. Key electrical parameters include ±0.5 LSB integral nonlinearity (INL) and differential nonlinearity (DNL), a maximum gain error of ±1 LSB over temperature, and a supply voltage range of 4.75V to 5.25V. The device features a 3-wire serial interface, an asynchronous clear input, and supports four-quadrant multiplication.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the component matches the specific Analog Devices part number LTC7543GKSW#TRPBF. Confirm the package type is the 16-lead Plastic SO (S Package). Ensure the operating temperature range meets the requirement of –40°C to 85°C. Check datasheet specifications for absolute maximum ratings before integration.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit serial DAC is required to replace legacy AD7543 or DAC-8143 designs. It is suitable for applications needing low power consumption and easy interfacing via a 3-wire serial bus. Consider the LTC8143 variant if daisy-chaining multiple DACs on a single bus is necessary, as it includes a serial data output.

Digital To Analog Converters Part Context

This part belongs to the LTC7543/LTC8143 family of improved industry standard serial 12-bit multiplying DACs. The LTC7543 provides a single-channel output configuration, while the LTC8143 adds a serial output for daisy-chaining capabilities. Both share similar accuracy characteristics and package options.

Digital To Analog Converters Replacement Considerations

The LTC7543 is designed as a superior direct replacement for the AD7543 and DAC-8143. It offers better stability over temperature and supply variations, lower sensitivity to output amplifier offset, and tighter timing specifications compared to the legacy parts.
