Overview
The LTC2633CTS8-LX12#TRPBF is a dual 12-bit voltage-output digital-to-analog converter in an 8-lead TSOT-23 package. It features an integrated reference with 10ppm/°C drift, providing a 2.5V full-scale output. The device operates from a single 2.7V to 5.5V supply and communicates via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical parameters include ±2.5LSB maximum INL, rail-to-rail output buffers, and guaranteed monotonicity over the –40°C to 125°C temperature range.
Feature Summary
- Dual 12-bit DACs with integrated 10ppm/°C reference for 2.5V full-scale output
- I2C-compatible serial interface operating at 100kHz or 400kHz clock rates
- Power-on reset configured to mid-scale in external reference mode
- Rail-to-rail output buffers with guaranteed monotonicity
Applications
- Mobile communications
- Process control and industrial automation
- Power supply margining
- Portable equipment
- Automotive systems
Procurement Notes
Verify the specific ordering suffixes against the manufacturer's current documentation to confirm package type, temperature grade, and power-on reset behavior. Ensure the I2C address configuration via the CA0 pin aligns with system requirements. Confirm that the tape and reel quantity matches the production needs.
Selection Notes
Select this component when a dual-channel solution with high accuracy and low drift is required in a compact package. The LX12 suffix indicates external reference mode operation with mid-scale power-on reset. Verify that the system supply voltage falls within the 2.7V to 5.5V range and that the I2C bus timing meets the specified setup and hold times.
Part Context
This part belongs to the LTC2633 family of dual DACs, which offers various resolutions (8, 10, 12 bits) and power-on reset options. The 'L' designation specifies the 2.5V internal reference full-scale voltage, while 'H' denotes 4.096V. The 'A' grade provides tighter linearity specifications compared to standard grades.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided datasheet. Consult Analog Devices for cross-reference information regarding alternative packages or updated revisions.
