Overview
The LTC2636HMS-LMI8#TRPBF is an octal, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. 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 monotonic over the –40°C to 125°C automotive temperature range. Communication occurs via a 3-wire SPI/MICROWIRE interface supporting clock rates up to 50MHz. This specific part number utilizes a 16-lead MSOP package and incorporates power-on reset logic that sets outputs to mid-scale in external reference mode.
Feature Summary
- Octal architecture with 8 independent 8-bit DAC channels
- Integrated 4.096V full-scale reference with ±10ppm/°C drift
- Rail-to-rail output buffers with ultralow crosstalk (<2.4nV•s)
- Automotive grade operation (-40°C to 125°C) in 16-lead MSOP package
Applications
- Process control and industrial automation systems
- Automatic test equipment requiring multi-channel output
- Portable battery-powered instrumentation
- Optical networking signal generation
Procurement Notes
Verify the H-grade designation confirms the –40°C to 125°C operating range and 4.5V minimum supply requirement. Confirm the MS suffix indicates the 16-lead MSOP package type. Ensure the TRPBF suffix matches the required tape and reel packaging quantity for automated assembly processes.
Selection Notes
Select this variant when an automotive temperature range is required alongside an internal 4.096V reference. The H-grade specification necessitates a supply voltage between 4.5V and 5.5V, unlike the L-grade which supports 2.7V. Choose the MX power-on reset option if mid-scale initialization in external reference mode is desired for system safety.
Part Context
This component belongs to the LTC2636 family of octal DACs available in 12-, 10-, and 8-bit resolutions. The family shares identical pinouts and interface protocols across DFN and MSOP packages. Variants differ primarily by resolution accuracy, internal reference voltage (2.5V or 4.096V), and specified operating temperature grades.
Replacement Considerations
LTC2636HMS-LMX8#PBF: Identical electrical specifications but resets to mid-scale in external reference mode upon power-up instead of internal reference mode.
