Overview
The LTC2636IMS-LMI10#PBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. 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 industrial temperature range (-40°C to 85°C), and double-buffered data latches. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. The MSOP package provides hardware clear (CLR) and asynchronous DAC update (LDAC) pins.
Feature Summary
- Octal 10-Bit Resolution with Integrated 2.5V Reference
- Rail-to-Rail Output Buffers Guaranteed Monotonic
- Industrial Temperature Range (-40°C to 85°C)
- SPI/MICROWIRE Interface with Hardware Clear and LDAC
Applications
- Process Control and Industrial Automation
- Portable Equipment
- Automotive Systems
Procurement Notes
Verify the specific ordering suffix #PBF indicates lead-free design compliance. Confirm the IMS designation corresponds to the 16-lead MSOP package and I-grade industrial temperature rating. Ensure the LMI10 suffix matches the required 2.5V full-scale internal reference and mid-scale power-on reset behavior.
Selection Notes
Select this part for applications requiring eight independent analog outputs with high accuracy in a compact surface-mount package. The 10-bit resolution balances cost and performance for general-purpose control loops. Verify that the 2.5V internal reference range meets system voltage requirements, as the H-grade variant offers 4.096V but requires higher supply voltages.
Part Context
This component belongs to the LTC2636 family of octal DACs, which also includes 8-bit and 12-bit variants. The IMS-LMI10 specifically denotes the industrial grade version in the MSOP package with 10-bit resolution, 2.5V internal reference, and mid-scale power-on reset configuration.
Replacement Considerations
Direct substitutes within the same family include LTC2636CDE-LMI10#PBF (commercial grade, DFN package) or LTC2636HMS-LMI10#PBF (automotive grade, higher temp range). Cross-package replacements require verifying pin compatibility between MSOP and DFN footprints.
