Overview
The LTC2632HTS8-LX12#TRPBF is a dual 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in an 8-lead TSOT-23 package. It features an integrated 2.5V full-scale reference with a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 2.7V to 5.5V and communicates via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. It includes rail-to-rail output buffers and is guaranteed monotonic. This specific variant incorporates a power-on reset function that sets the output to mid-scale when operating in external reference mode.
Feature Summary
- Dual 12-bit DACs with integrated 2.5V internal reference
- Power-on reset to mid-scale in external reference mode
- 3-wire serial interface with 50MHz clock capability
- 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 complete part number including the suffix #TRPBF to confirm tape and reel packaging specifications. Confirm that the LX designation aligns with system requirements for external reference mode power-on reset behavior. Ensure supply voltage sequencing respects the REF pin limits during power-up to maintain device reliability.
Selection Notes
Select this component if a 2.5V full-scale output range is required with an integrated low-drift reference. The LX suffix is critical for applications needing mid-scale initialization during power-up when using an external reference source. Verify that the 2.7V minimum supply voltage meets the system's lowest operating condition.
Part Context
This part belongs to the LTC2632 family of dual DACs available in various resolutions and accuracy grades. The HTS8 indicates an automotive temperature grade (-40°C to 125°C) in an 8-lead TSOT-23 package. The LX code specifically defines the power-on reset behavior for external reference configurations within this product line.
Replacement Considerations
Direct substitutes include other LTC2632 variants such as LTC2632ACTS8-LX12#TRMPBF or LTC2632HTS8-LZ12#TRPBF, provided the power-on reset behavior and temperature grade match the design requirements.
