LTC2635CMSE-LZ10#TRPBF

Overview

The LTC2635CMSE-LZ10#TRPBF is a quad 10-bit voltage-output digital-to-analog converter (DAC) in a 10-lead MSOP 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 from a single 2.7V to 5.5V supply and includes rail-to-rail output buffers guaranteed monotonic over the commercial temperature range of 0°C to 70°C. Communication occurs via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. A power-on reset circuit defaults outputs to zero-scale.

Feature Summary

• Quad 10-bit resolution with ±1 LSB maximum INL error
• Integrated 2.5V precision reference (10ppm/°C drift)
• Rail-to-rail output buffers with ultralow crosstalk (3nV•s)
• Power-on reset to zero-scale in internal reference mode

Applications

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

Procurement Notes

Verify the MSE package designation and LZ10 suffix configuration against the official Analog Devices ordering guide. Confirm that the commercial temperature grade (C) meets the operational requirements, as automotive grades (H) are available for wider ranges. Ensure the tape and reel quantity matches project needs.

Selection Notes

Select this part when four independent 10-bit channels are required in a compact MSOP footprint. The 2.5V full-scale range suits low-voltage systems operating between 2.7V and 5.5V. Choose the LZ variant if a zero-scale power-on reset state is necessary for system safety or initialization protocols.

Part Context

This component belongs to the LTC2635 family, which offers 8-, 10-, and 12-bit resolutions. The CMSE suffix indicates the commercial temperature grade and MSOP package, while LZ denotes the zero-scale reset option. Other variants include LMI (mid-scale reset) and H-grade parts for automotive applications.

Replacement Considerations

Direct substitutes within the same family include LTC2635CMSE-LZ12#TRPBF (12-bit) and LTC2635CMSE-LZ8#TRPBF (8-bit). For mid-scale reset functionality, consider LTC2635CMSE-LMI10#TRPBF. Automotive equivalents are available in the H-grade series.
