Overview
The LTC2636IMS-LZ12#PBF is an octal 12-bit voltage-output digital-to-analog converter (DAC) in a 16-lead MSOP package. It features an integrated 10ppm/°C reference with a 2.5V full-scale output. The device operates from a single 2.7V to 5.5V supply and includes rail-to-rail output buffers guaranteed monotonic over the –40°C to 85°C industrial temperature range. It communicates via a 50MHz SPI-compatible interface and incorporates power-on reset logic that clears outputs to zero-scale upon initialization.
Feature Summary
- Octal 12-bit architecture with integrated 10ppm/°C reference
- 2.5V full-scale output with 2.7V to 5.5V single-supply operation
- Power-on reset to zero-scale for consistent system initialization
- 50MHz SPI/MICROWIRE compatible serial interface
Applications
- Mobile Communications
- Process Control and Industrial Automation
- Automatic Test Equipment
- Portable Equipment
- Automotive Systems
Procurement Notes
Verify the specific suffix LZ12 confirms the 12-bit resolution, zero-scale power-on reset behavior, and 2.5V internal reference configuration. Ensure the MSOP package variant matches the required pinout, specifically noting the presence of CLR and LDAC control pins unique to this package type compared to the DFN option.
Selection Notes
Select this part when eight independent 12-bit channels are required with tight integral nonlinearity specifications. The zero-scale reset feature is critical for applications where downstream circuits must remain inactive during power-up. Verify that the 2.5V internal reference range meets the system's voltage requirements without needing external buffering.
Part Context
This component belongs to the LTC2636 family, which offers variations in resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), and power-on reset states. The IMS designation indicates the 16-lead MSOP package, while the LZ12 suffix specifies the 12-bit resolution and zero-scale reset mode within the low-voltage (L) sub-family.
Replacement Considerations
Direct substitutes include other LTC2636 variants such as LTC2636IMH-LZ12#PBF for automotive grade (-40°C to 125°C) or LTC2636IDE-LZ12#PBF for DFN packaging. Cross-model replacements require verifying pin compatibility and ensuring the replacement maintains the 12-bit resolution and zero-scale reset functionality.
