LTC2633CTS8-LX10#TRMPBF

Overview

The LTC2633CTS8-LX10#TRMPBF is a dual 10-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 2.7V to 5.5V supply and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, rail-to-rail output buffers, and guaranteed monotonicity over the commercial temperature range of 0°C to 70°C.

Feature Summary

• Dual 10-bit DACs with integrated 2.5V precision reference (10ppm/°C drift)
• I²C-compatible serial interface with selectable internal or external reference
• Rail-to-rail output buffers with ±1 LSB maximum INL error
• Power-on reset to mid-scale in external reference mode

Applications

• Mobile communications
• Process control and industrial automation
• Portable equipment

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel configuration, distinct from the standard 2500-unit reel. Confirm the 'C' grade corresponds to the commercial temperature range (0°C to 70°C) and that the 'X' power-on reset code aligns with system initialization requirements for external reference operation.

Selection Notes

Select this part for applications requiring dual channels with low power consumption (0.4mA at 3V) and precise voltage generation. Ensure the supply voltage remains within 2.7V to 5.5V. If higher accuracy is needed, consider the 'A' grade variant; if automotive temperature ranges are required, select the 'H' grade version instead.

Part Context

This component belongs to the LTC2633 family of dual DACs, which offers various resolution options (8-, 10-, and 12-bit) and power-on reset configurations. The LTS8 package designation refers to the 8-lead ThinSOT™ plastic package, providing a compact footprint suitable for space-constrained designs while maintaining electrical performance.

Replacement Considerations

Direct replacements within the same family include LTC2633CTS8-LI10#TRMPBF (internal reference reset) or LTC2633CTS8-LZ10#TRMPBF (zero-scale reset). For higher accuracy, the LTC2633ATS8-LX10#TRMPBF offers improved linearity. Cross-family replacements require verification of pin compatibility and interface protocols.
