Overview
The LTC2632HTS8-LZ8#TRPBF 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 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single supply 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 a power-on reset circuit that clears outputs to zero-scale upon initialization. The DACs are guaranteed monotonic and feature rail-to-rail output buffers.
Feature Summary
- Dual 8-bit Voltage Output DACs with Integrated 2.5V Reference
- SPI/MICROWIRE Compatible 3-Wire Serial Interface (Up to 50MHz)
- Power-On Reset to Zero-Scale for Consistent Initialization
- Guaranteed Monotonic Operation with Rail-to-Rail Outputs
Applications
- Mobile Communications
- Process Control and Industrial Automation
- Automatic Test Equipment
- Portable Equipment
- Automotive Systems
Procurement Notes
Verify the specific ordering suffix #TRPBF corresponds to the tape and reel packaging configuration required for automated assembly. Confirm that the LTS8 package designation matches the footprint constraints of the target PCB design. Ensure the automotive temperature grade (H) aligns with the operational environment specifications of the end application.
Selection Notes
Select this part when a dual-channel, low-pin-count DAC with an internal reference is required for space-constrained designs. The 8-bit resolution is suitable for applications where high precision is not critical but cost and simplicity are priorities. Verify that the 2.5V full-scale range meets the input requirements of downstream circuits or ADCs.
Part Context
This component belongs to the LTC2632 family, which offers various combinations of resolution (8, 10, 12-bit), accuracy grades, and power-on reset behaviors. The 'L' indicates a 2.5V full-scale internal reference, while 'Z' specifies the zero-scale power-on reset mode. The 'H' denotes the extended automotive temperature range (-40°C to 125°C).
Replacement Considerations
Direct substitutes within the same family include other LTC2632 variants with different resolutions or reset modes, such as LTC2632HTS8-LZ12#TRPBF for 12-bit resolution. Cross-family replacements require matching interface compatibility and supply voltage ranges.
