Overview
The LTC2635HMSE-LMX12#PBF is a quad 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, 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 and is guaranteed monotonic over the automotive temperature range of –40°C to 125°C. Communication occurs via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. The LMX suffix indicates power-on reset to mid-scale in external reference mode.
Feature Summary
- Quad 12-bit resolution with maximum INL error of ±2.5 LSB
- Integrated 4.096V full-scale reference with 10ppm/°C drift
- Rail-to-rail output buffers with ultralow crosstalk (3nV•s)
- Power-on reset to mid-scale for external reference configurations
Applications
- Process control and industrial automation
- Portable equipment
- Automotive systems
Procurement Notes
Verify the specific ordering suffixes against the manufacturer's official documentation to confirm package type, temperature grade, and power-on reset behavior. Ensure compatibility with system voltage requirements, as the H-grade variant requires a minimum supply of 4.5V. Confirm that the MSOP package footprint matches the PCB design constraints.
Selection Notes
Select this component when four independent 12-bit DAC channels are required in a compact surface-mount package. The H-grade designation ensures operation within the automotive temperature range (-40°C to 125°C). Choose the LMX option if the application demands a mid-scale output initialization upon power-up when using an external reference voltage source.
Part Context
This part belongs to the LTC2635 family, which also includes 8-bit and 10-bit variants (LTC2635-8/-10) and QFN package options (LTC2635UD). The HMSE designation specifically identifies the Automotive temperature grade (H), MSOP package (MSE), and the LMX power-on reset configuration.
Replacement Considerations
Direct replacements within the same family include LTC2635HMSE-LMI12#PBF (internal reference reset) or LTC2635HMSE-HZ12#PBF (zero-scale reset). For different resolutions, consider LTC2635HMSE-LMX10#PBF or LTC2635HMSE-LMX8#PBF.
