Overview
The LTC2633HTS8-LI8 is a dual-channel, 8-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 utilizes a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key specifications include rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C temperature range, and a power-on reset function that initializes outputs to mid-scale in internal reference mode.
Feature Summary
- Dual 8-bit DAC channels with integrated 2.5V full-scale reference
- I2C-compatible serial interface with selectable clock rates up to 400kHz
- Rail-to-rail output buffers with ±0.5 LSB INL accuracy
- Power-on reset to mid-scale or zero-scale options
Applications
- Mobile communications systems
- Process control and industrial automation
- Portable equipment requiring low power consumption
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current product selection guide to confirm package type, temperature grade, and power-on reset configuration. Ensure compatibility with system voltage requirements, as the 'H' grade supports –40°C to 125°C while 'C' grade is limited to 0°C to 70°C.
Selection Notes
Select this component for applications requiring dual independent voltage outputs in a compact 8-lead TSOT-23 package. The 8-bit resolution is suitable for cost-sensitive designs where high precision is not critical. Confirm that the 2.5V internal reference meets the required output swing; otherwise, consider external reference operation or higher-resolution variants within the family.
Part Context
This part belongs to the LTC2633 family of dual DACs, which also includes 10-bit and 12-bit resolutions. Variants are available with different power-on reset behaviors and temperature grades. The 'LI8' designation indicates the 8-bit resolution, internal reference mode, and mid-scale power-on reset configuration.
Replacement Considerations
Direct replacements within the same family include LTC2633LTCS8-LI8 (commercial temp) or LTC2633HTS8-HI8 (higher full-scale voltage). Cross-family replacements require verification of pin compatibility and software register mapping.
