Overview
The LTC2636IMS-HZ12#PBF is an octal 12-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 monotonicity over the –40°C to 85°C temperature range, and a 3-wire SPI/MICROWIRE-compatible interface supporting clock rates up to 50MHz. Power-on reset defaults to zero-scale in internal reference mode.
Feature Summary
- Octal architecture with 12-bit resolution and 4.096V full-scale output
- Integrated 10ppm/°C precision reference
- Rail-to-rail output buffers with guaranteed monotonicity
- 3-wire serial interface with 50MHz clock rate
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
- Automotive systems
- Optical networking
Procurement Notes
Verify package type as MSOP-16 for this specific suffix. Confirm power-on reset behavior matches zero-scale requirements. Ensure supply voltage stays within 4.5V to 5.5V limits. Check RoHS compliance status if required by project specifications.
Selection Notes
Select this part when eight independent 12-bit channels are needed with high accuracy. The H-grade variant requires 4.5V minimum supply. Consider the IMS package for industrial temperature ranges. Verify external reference compatibility if not using the internal 4.096V setting.
Part Context
Part of the LTC2636 family offering octal DACs in DFN and MSOP packages. Variants differ by resolution (8/10/12-bit), reset behavior (MI/MX/Z), and full-scale voltage (L/H). This specific model combines 12-bit resolution with the H-series 4.096V reference and industrial temperature grade.
Replacement Considerations
Direct substitutes include other LTC2636 variants with matching pinouts but different resolutions or reset behaviors. Cross-family replacements require verifying interface compatibility and supply voltage ranges.
