LTC2632HTS8-LZ10#TRMPBF

Overview

The LTC2632HTS8-LZ10#TRMPBF is a dual 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. 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 utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. It includes rail-to-rail output buffers, guaranteed monotonicity, and a power-on reset function that clears outputs to zero-scale. The component is housed in an 8-lead TSOT-23 package.

Feature Summary

• Dual 10-bit DACs with integrated 2.5V full-scale reference
• Low drift reference: 10ppm/°C temperature coefficient
• Power-on reset to zero-scale for consistent initialization
• 3-wire SPI/MICROWIRE interface supporting up to 50MHz clock

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel configuration. Confirm the HTS8 designation corresponds to the Automotive temperature grade (-40°C to 125°C) and TSOT-23 package type as defined in the manufacturer's selection guide. Ensure compatibility with system power supply ranges between 2.7V and 5.5V.

Selection Notes

Select this part when a dual-channel DAC with zero-scale power-up behavior is required. The 10-bit resolution offers a balance between accuracy and data throughput. Choose the LZ variant specifically if the application demands the outputs to default to ground potential upon power-up, rather than mid-scale. Verify that the 2.5V internal reference range meets the system's output voltage requirements.

Part Context

This component belongs to the LTC2632 family, which includes 8-, 10-, and 12-bit variants. The 'H' suffix denotes the automotive temperature grade (-40°C to 125°C), while 'L' indicates the 2.5V full-scale internal reference. The 'Z' suffix specifies the power-on reset to zero-scale mode. Other family members include the LTC2632ACTS8-LI12#TRMPBF, which differs in resolution, reset behavior, and commercial temperature rating.

Replacement Considerations

Publicly confirmed substitutes within the same family include the LTC2632HTS8-LZ12#TRMPBF (12-bit resolution) or the LTC2632HTS8-LZ8#TRMPBF (8-bit resolution). These parts share identical pinouts, packages, and core functionality but differ in bit depth and associated linearity specifications.
