Overview
The LTC2633HTS8-HI8 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 4.096V and operates on a single 4.5V 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 DACs with integrated 4.096V precision reference
- I²C interface with selectable slave addresses via CA0 pin
- Rail-to-rail output buffers with ±0.8% gain error
- 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 HTS8-HI8 against the manufacturer's current product selection guide to confirm package type, temperature grade, and power-on reset configuration. Ensure compatibility with the required supply voltage range of 4.5V to 5.5V for the H-grade variant.
Selection Notes
Select this component when dual-channel 8-bit resolution is sufficient for the application. The H-grade designation indicates operation from 4.5V to 5.5V with a 4.096V full-scale output. Consider the HI12 equivalent if 12-bit resolution is required, noting the change in INL performance and supply voltage requirements.
Part Context
This part belongs to the LTC2633 family of dual DACs, which also includes 10-bit and 12-bit variants (LTC2633-10, LTC2633-12). The family shares the same 8-lead TSOT-23 package and I²C interface architecture, differing primarily in resolution, linearity specifications, and internal reference voltage scaling.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other LTC2633 variants based on resolution and supply voltage requirements.
