LTC2635CMSE-LMO10#TRPBF

Overview

The LTC2635CMSE-LMO10#TRPBF is a quad 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 operates on a single 2.7V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the temperature range, and communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. This specific variant utilizes a 10-lead MSOP package and incorporates a power-on reset circuit configured to set outputs to high impedance upon startup.

Feature Summary

• Quad 10-bit resolution with integrated 2.5V precision reference
• Power-on reset to High-Impedance state for LMO suffix variants
• Rail-to-rail output buffers with ultralow crosstalk (3nV•s)
• I2C interface operating in standard and fast modes

Applications

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

Procurement Notes

Verify the ordering suffix 'LMO' corresponds to the High-Impedance power-on reset configuration as defined in the official selection guide. Confirm the 'MSE' designation indicates the 10-lead MSOP package type. Ensure the '#TRPBF' suffix matches the required tape and reel packaging specifications for the manufacturing process.

Selection Notes

Select this component when four independent 10-bit DAC channels are required within a compact footprint. The LMO suffix is necessary if the application demands that all DAC outputs enter a high-impedance state immediately after power-up. The internal 2.5V reference simplifies design by eliminating external reference components while maintaining 10ppm/°C drift characteristics.

Part Context

This part belongs to the LTC2635 family of quad DACs available in 8-, 10-, and 12-bit resolutions. The CMSE prefix denotes the Commercial temperature grade (0°C to 70°C) and the 10-lead MSOP package. Other variants include the H-grade for automotive temperatures and different packages such as QFN. The LMO suffix specifically defines the power-on reset behavior distinct from other reset options like zero-scale or mid-scale.

Replacement Considerations

Direct replacements within the same family include LTC2635CMSE-LMI10#TRPBF (Mid-Scale reset) or LTC2635CMSE-LZ10#TRPBF (Zero-Scale reset). Verify that the alternative reset behavior meets the system requirements before substitution.
