Overview
The LTC2635HMSE-LMX12#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 4.096V and operates on a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C automotive temperature range, and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Power-on reset options include mid-scale for external reference mode.
Feature Summary
- Quad 12-bit resolution with ±2.5 LSB maximum INL error
- Integrated 4.096V full-scale reference with 10ppm/°C drift
- Automotive temperature grade (-40°C to 125°C)
- Power-on reset to mid-scale in external reference mode
Applications
- Process control and industrial automation
- Portable equipment
- Automotive systems
Procurement Notes
Verify the specific ordering suffix LMX12#TRPBF against the manufacturer's current documentation to confirm power-on reset behavior and tape-and-reel specifications. Ensure the design supports the required 4.5V to 5.5V supply range for the H-grade variant.
Selection Notes
Select this part when a quad-channel DAC with high accuracy and automotive reliability is required. The H-grade designation ensures operation at higher supply voltages (4.5V–5.5V) compared to the L-grade. Verify that the I²C address configuration pins (CA0-CA2) meet system addressing requirements.
Part Context
This component belongs to the LTC2635 family of quad DACs, which also includes 10-bit and 8-bit variants. The HMSE suffix indicates the Automotive temperature grade and MSOP packaging, while LMX12 specifies the 12-bit resolution and mid-scale reset behavior for external reference configurations.
Replacement Considerations
Direct replacements within the same family include LTC2635CMSE-LMX12#TRPBF for commercial temperature ranges or other resolutions like LTC2635HMSE-LMX10#TRPBF if lower resolution suffices.
