LTC2632HTS8-HZ10#TRMPBF

Overview

The LTC2632HTS8-HZ10#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 4.096V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface for communication, supporting clock rates up to 50MHz. The part includes rail-to-rail output buffers and guarantees monotonicity over the specified range. Upon power-up, the outputs reset to zero-scale in internal reference mode.

Feature Summary

• Dual 10-bit DACs with integrated 4.096V precision reference
• Rail-to-rail output buffers with guaranteed monotonicity
• Power-on reset to zero-scale in internal reference mode
• 3-wire SPI/MICROWIRE interface with 50MHz clock rate

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-piece tape and reel packaging configuration. Confirm that the H-grade designation corresponds to the automotive temperature range of –40°C to 125°C. Ensure compatibility with the required 4.5V to 5.5V supply voltage constraints for the H-series variant before procurement.

Selection Notes

Select this model when a 4.096V full-scale output is required with zero-scale initialization upon power-up. The HZ10 suffix denotes the 10-bit resolution, high-voltage range, and zero-scale reset option. Compare against the HI10 variant if mid-scale reset is preferred, or the LZ10 variant if lower voltage operation with 2.5V full-scale is sufficient.

Part Context

This component belongs to the LTC2632 family of dual DACs available in 8-, 10-, and 12-bit resolutions. The HTS8 package identifies it as an 8-lead ThinSOT plastic package. The H series specifically supports higher supply voltages starting at 4.5V, distinguishing it from the L series which operates down to 2.7V.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Verify pinout and electrical specifications against alternative dual DACs if cross-referencing is necessary.
