LTC2633CTS8-LX10

Overview

The LTC2633CTS8-LX10 is a dual-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. 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. It includes rail-to-rail output buffers, guaranteed monotonicity over the operating temperature range, and a power-on reset function that sets outputs to mid-scale in external reference mode.

Feature Summary

• Dual 10-bit DACs with integrated 2.5V precision reference (10ppm/°C drift)
• I²C interface with selectable internal or external reference input
• Power-on reset configured for mid-scale output in external reference mode
• Rail-to-rail output buffers with guaranteed monotonic operation

Applications

• Mobile communications systems
• Process control and industrial automation
• Portable equipment requiring low power consumption
• Automotive electronic modules

Procurement Notes

Verify the specific ordering suffix 'LX10' against the manufacturer's current product selection guide to confirm the power-on reset behavior and resolution match project requirements. Ensure the design supports the required 2.7V to 5.5V supply range and I²C bus timing specifications for reliable communication.

Selection Notes

Select this component when a dual-channel DAC with a fixed 2.5V internal reference and mid-scale power-on reset in external reference mode is required. Compare INL performance against the 'A' grade variant if tighter linearity specifications are necessary for the application.

Part Context

This part belongs to the LTC2633 family of dual DACs available in 8-, 10-, and 12-bit resolutions. The 'CTS8' designation indicates the commercial temperature grade (0°C to 70°C) and the 8-lead TSOT-23 package. The 'LX10' suffix specifies the 10-bit resolution, 2.5V full-scale internal reference, and mid-scale power-on reset configuration.

Replacement Considerations

Direct replacements within the same family include LTC2633CTS8-LI10 (internal reference reset) or LTC2633CTS8-LZ10 (zero-scale reset). For higher accuracy, consider the LTC2633A series variants.
