LTC2633HTS8-LX12#TRMPBF

Digital To Analog Converters Overview

The LTC2633HTS8-LX12#TRMPBF is a dual 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in an 8-lead TSOT-23 package. It features an integrated precision reference with a full-scale output of 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 2.7V to 5.5V and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1.5 LSB, rail-to-rail output buffers, and guaranteed monotonicity over the –40°C to 125°C temperature range.

Digital To Analog Converters Feature Summary

• Dual 12-bit DACs with integrated 2.5V precision reference (10ppm/°C drift)
• I²C interface with selectable power-on reset to mid-scale in external reference mode
• Rail-to-rail output buffers with ±1.5 LSB maximum INL error
• Operates from 2.7V to 5.5V supply with low power consumption (0.4mA at 3V)

Digital To Analog Converters Applications

• Mobile communications
• Process control and industrial automation
• Power supply margining
• Portable equipment
• Automotive systems

Digital To Analog Converters Procurement Notes

Verify the #TRMPBF suffix indicates a 500-unit tape and reel packaging configuration, distinct from the standard 2,500-unit reel. Confirm the LX12 designation corresponds to the specific power-on reset behavior for external reference mode applications. Ensure compatibility with the required operating temperature range and supply voltage constraints during sourcing.

Digital To Analog Converters Selection Notes

Select this part when a dual-channel 12-bit DAC with a 2.5V internal reference is required in a compact TSOT-23 package. The LX code specifies a power-on reset to mid-scale in external reference mode; verify this matches system initialization requirements compared to zero-scale or high-impedance options. Ensure the application supply voltage falls within the 2.7V to 5.5V range for specified performance.

Digital To Analog Converters Part Context

This component belongs to the LTC2633 family of dual I²C DACs, which offers various combinations of resolution, reference voltage, and power-on reset states. The HTS8 variant denotes the automotive temperature grade (-40°C to 125°C) in the TSOT-23 package. The LX12 suffix specifically configures the device for 12-bit resolution with mid-scale reset in external reference mode.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include LTC2633HTS8-LI12#TRMPBF (internal reference reset) or LTC2633HTS8-LZ12#TRMPBF (zero-scale reset). For different resolutions, consider LTC2633HTS8-LX10#TRMPBF (10-bit) or LTC2633HTS8-LX8#TRMPBF (8-bit), noting changes in linearity specifications.
