LTC8043FS8#TRPBF

Digital To Analog Converters Overview

The LTC8043FS8#TRPBF is a serial-input 12-bit multiplying digital-to-analog converter (DAC) in an 8-lead SOIC package. It serves as a pin-compatible replacement for the DAC-8043 and MAX543, offering improved accuracy and stability over temperature and supply variations. The device features a 3-wire serial interface suitable for remote or isolated applications. Key electrical specifications include ±0.5 LSB INL/DNL, ±1 LSB maximum gain error at 25°C, and a settling time of 0.25 µs. It operates on a single 5V supply with low power consumption.

Digital To Analog Converters Feature Summary

• 12-bit resolution with ±0.5 LSB INL/DNL and ±1 LSB gain error
• 3-wire serial interface compatible with SPI/MICROWIRE protocols
• Supports 2-quadrant and 4-quadrant multiplication modes
• Low output capacitance (60pF typical) and low power consumption

Digital To Analog Converters Applications

• Process control and industrial automation systems
• Remote microprocessor-controlled instrumentation
• Digitally controlled filters and programmable gain amplifiers
• Automatic test equipment requiring precise voltage/current references

Digital To Analog Converters Procurement Notes

Verify that the #TRPBF suffix indicates tape-and-reel packaging rather than tube packaging when sourcing components. Confirm the FS8 designation corresponds to the extended industrial temperature range (-40°C to +85°C) and the specific SOIC-8 footprint required for your PCB layout. Ensure compatibility with existing design files if replacing legacy DAC-8043 units.

Digital To Analog Converters Selection Notes

Select this component when a direct pin-compatible upgrade from DAC-8043 or MAX543 is required with enhanced linearity and lower output capacitance. The 3-wire interface minimizes GPIO usage compared to parallel DACs. Consider the 0.25 µs settling time for high-speed updating requirements and verify that the current-output architecture fits the downstream amplifier configuration.

Digital To Analog Converters Part Context

The LTC8043 series includes variants such as the ES8 (tube) and FN8 (PDIP). The FS8 variant specifically denotes the SOIC-8 package with extended temperature grading. The #TRPBF suffix identifies the reel-packaged version compliant with RoHS standards. This part belongs to Analog Devices' portfolio of precision data converters designed for industrial signal chain applications.

Digital To Analog Converters Replacement Considerations

The datasheet explicitly identifies the LTC8043 as a superior pin-compatible replacement for the DAC-8043 and MAX543. Designers should verify that the improved timing specifications and lower output capacitance do not require adjustments to existing feedback networks or drive circuits.
