Overview
The LTC2635CMSE-LMI12#TRPBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc., housed in a 10-lead MSOP package. 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 commercial temperature range of 0°C to 70°C, and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes.
Feature Summary
- Quad 12-bit resolution with maximum INL error of ±2.5 LSB
- Integrated 2.5V full-scale precision reference with 10ppm/°C drift
- Rail-to-rail buffered outputs with ultralow crosstalk (3nV•s)
- Power-on reset configurable to mid-scale in internal reference mode
Applications
- Mobile communications systems
- Process control and industrial automation
- Portable equipment requiring low power consumption
Procurement Notes
Verify the specific suffix 'MSE' corresponds to the 10-lead MSOP package and 'LMi12' indicates the mid-scale power-on reset option for the 12-bit L-grade variant. Confirm the '#TRPBF' designation matches the required tape and reel quantity of 2,500 pieces and lead-free status before procurement.
Selection Notes
Select this part when four independent 12-bit DAC channels are required in a compact surface-mount package. Ensure the application operates within the 2.7V to 5.5V supply range and 0°C to 70°C temperature limits. Consider the H-grade version if automotive temperature ranges (-40°C to 125°C) or a 4.096V full-scale output are necessary.
Part Context
This component belongs to the LTC2635 family of quad DACs, which also offers 10-bit and 8-bit resolutions. Variants include QFN packages and different power-on reset behaviors (zero-scale, high-impedance). The CMSE-LMi12 specifically denotes the commercial grade, MSOP package, and mid-scale reset configuration.
Replacement Considerations
Direct pin-compatible replacements within the same family include LTC2635CMSE-LZ12#TRPBF (zero-scale reset) or LTC2635CMSE-HMI12#TRPBF (automotive grade, 4.096V FS). Verify that the alternative's power-on state and full-scale voltage meet the system requirements.
