Overview
The LTC2634CUD-LMI8#PBF is a quad 8-bit voltage output digital-to-analog converter (DAC) in a 16-lead QFN package. It features an integrated precision reference with a full-scale output of 2.5V and operates from a single 2.7V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the temperature range, and a power-on reset to mid-scale in internal reference mode. Communication is handled via an SPI/MICROWIRE compatible 3-wire serial interface supporting clock rates up to 50MHz.
Feature Summary
- Quad 8-bit DACs with integrated 2.5V full-scale reference
- Rail-to-rail output buffers with guaranteed monotonicity
- Power-on reset to mid-scale in internal reference mode
- SPI/MICROWIRE compatible 3-wire serial interface
Applications
- Mobile Communications
- Process Control and Industrial Automation
- Automatic Test Equipment
- Portable Equipment
- Automotive
Procurement Notes
Verify the specific ordering suffix #PBF indicates lead-free construction compliant with RoHS standards. Confirm the C temperature grade corresponds to the commercial range of 0°C to 70°C. Ensure the LMI designation matches the required mid-scale power-on reset behavior for internal reference applications.
Selection Notes
Select this part when a quad 8-bit resolution is sufficient for the application. The LMI suffix ensures the outputs reset to mid-scale upon power-up, which may be necessary if downstream circuits are sensitive to zero-scale states during initialization. Verify that the 2.5V full-scale range meets the system voltage requirements.
Part Context
This component belongs to the LTC2634 family, which offers 12-, 10-, and 8-bit resolutions in both QFN and MSOP packages. The CUD suffix identifies the commercial temperature grade and 16-lead QFN packaging. The LMI suffix specifies the mid-scale reset configuration for internal reference operation.
Replacement Considerations
Other members of the LTC2634 family, such as LTC2634CUD-LMX8#PBF or LTC2634CUD-LZ8#PBF, share the same pinout and interface but differ in power-on reset behavior or reference mode selection.
