LTC1456IS8#TRPBF

Digital To Analog Converters Overview

The LTC1456IS8#TRPBF is a single-supply, rail-to-rail voltage output, 12-bit digital-to-analog converter (DAC) in an SO-8 package. It features a buffered true rail-to-rail voltage output and an asynchronous clear input. The device includes a built-in 2.048V reference, resulting in a full-scale output of 4.095V. It operates on a 4.5V to 5.5V supply with a typical power dissipation of 2.2mW. Key electrical specifications include a maximum DNL error of 0.5LSB, settling time of 14µs to 0.5LSB, and a 3-wire cascadable serial interface.

Digital To Analog Converters Procurement Notes

Verify the ordering suffix #TRPBF indicates tape-and-reel packaging when sourcing this component. Confirm that the IS8 variant corresponds to the industrial temperature range (-40°C to +85°C) and the S8 plastic SOIC package. Ensure compatibility with the required 4.5V to 5.5V supply voltage for specified performance.

Digital To Analog Converters Selection Notes

Select the LTC1456IS8#TRPBF for applications requiring a single-supply, space-saving SO-8 DAC with internal reference capabilities. The device is suitable for battery-powered systems due to its low power consumption of 2.2mW. Consider the 3-wire serial interface and daisy-chain capability via the DOUT pin if multiple channels are needed in the design.

Digital To Analog Converters Part Context

The LTC1456 is part of Analog Devices' family of micropower DACs. Related parts include the LTC1451, which exposes the reference voltage, and the LTC1446/LTC1446L dual-channel variants. The IS8 designation specifies the industrial temperature grade and surface-mount SOIC-8 package format within this product line.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include the LTC1456CS8#PBF for commercial temperature range or LTC1456IN8#PBF for PDIP packaging. For multi-channel requirements, consider the LTC1446 dual-channel DAC or the LTC1458 quad-channel DAC.
