LTC2635CMSE-LZ8#TRPBF

Overview

The LTC2635CMSE-LZ8#TRPBF is a quad 8-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 is handled 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 8-bit DACs with integrated 2.5V precision reference (10ppm/°C)
• Rail-to-rail output buffers with maximum INL error of ±0.5 LSB
• Power-on reset to zero-scale with low noise (0.75mV P-P, 0.1Hz to 200kHz)
• I²C interface with selectable slave addresses via CA0-CA2 pins

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates lead-free construction and tape-and-reel packaging containing 2,500 pieces. Confirm the MSE package designation corresponds to the 10-lead MSOP form factor. Ensure the C-grade temperature rating aligns with the intended operating environment of 0°C to 70°C.

Selection Notes

Select this part for applications requiring four independent 8-bit channels with a fixed 2.5V internal reference. The LZ8 suffix specifies a zero-scale power-on reset state. Consider the LTC2635-H variant if a 4.096V full-scale output or automotive temperature range (-40°C to 125°C) is required instead.

Part Context

This component belongs to the LTC2635 family of quad DACs, which also offers 10-bit and 12-bit resolutions. The CMSE prefix denotes the Commercial temperature grade and MSOP package. Other variants include the H-grade for automotive use and different reset configurations such as mid-scale (MI/MX) or high-impedance (MO).
