Overview
The LTC2632HTS8-LI8 is a dual 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in an 8-lead TSOT-23 package. It features an integrated precision reference with a full-scale output of 4.096V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. Power-on reset defaults to mid-scale in internal reference mode. The DACs include rail-to-rail output buffers and are guaranteed monotonic.
Feature Summary
- Dual 8-bit resolution with integrated 4.096V precision reference
- SPI/MICROWIRE 3-wire serial interface with 50MHz clock rate
- Power-on reset to mid-scale in internal reference mode
- Rail-to-rail output buffers with guaranteed monotonicity
Applications
- Mobile communications
- Process control and industrial automation
- Automatic test equipment
- Portable equipment
- Automotive systems
Procurement Notes
Verify the specific ordering suffix for tape and reel quantities. Confirm that the automotive temperature grade (-40°C to 125°C) matches the application requirements. Ensure the supply voltage range of 4.5V to 5.5V is compatible with the system design before procurement.
Selection Notes
Select this component when a dual-channel, low-pin-count DAC with an integrated high-accuracy reference is required. The 8-bit resolution is suitable for applications not requiring high precision. Verify that the 4.5V minimum supply voltage meets the system's power constraints compared to the 2.7V capable LTC2632-L variants.
Part Context
This part belongs to the LTC2632 family of dual DACs available in 8-, 10-, and 12-bit resolutions. The 'H' designation indicates the 4.096V full-scale internal reference variant, while 'LI' specifies the mid-scale power-on reset behavior in internal reference mode. The 'TS8' denotes the 8-lead TSOT-23 package type.
Replacement Considerations
Direct replacements within the same family include LTC2632HTS8-HI8 or LTC2632HTS8-ZI8, depending on the desired power-on reset state. For lower voltage operation, consider the LTC2632L series, though this requires verifying the supply voltage compatibility.
