Overview
The LTC2635CMSE-LMI10#PBF 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 is handled via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Power-on reset defaults to mid-scale in internal reference mode.
Feature Summary
- Quad 10-bit resolution with ±1 LSB maximum INL error
- Integrated 2.5V full-scale reference with 10ppm/°C drift
- I2C-compatible interface with selectable slave addresses
- Power-on reset to mid-scale or high-impedance states
Applications
- Mobile communications
- Process control and industrial automation
- Portable equipment
Procurement Notes
Verify the specific suffix LMI10 confirms the 10-bit resolution, mid-scale power-on reset behavior, and 2.5V internal reference configuration. Confirm the MSE package designation matches the required 10-lead MSOP footprint for PCB layout compatibility.
Selection Notes
Select this part when four independent 10-bit channels are required with low noise and precise offset calibration. Ensure the system supply voltage remains within the 2.7V to 5.5V range compatible with the 'L' grade variant. Consider the H-grade if a 4.096V full-scale output is necessary.
Part Context
This component belongs to the LTC2635 family of quad DACs, which also offers 8-bit and 12-bit resolutions. The family shares identical pinouts and interface protocols across resolutions, allowing for design flexibility while maintaining consistent board space requirements.
Replacement Considerations
Direct substitutes include other LTC2635 variants with different resolutions (LTC2635-LMI12, LTC2635-LMI8) or reset configurations (LZ, LMO). Cross-family replacements require verification of I2C address compatibility and register mapping.
