LTC2632HTS8-HZ10#TRPBF

Overview

The LTC2632HTS8-HZ10#TRPBF is a dual 10-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 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. Key specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, rail-to-rail output buffers, and guaranteed monotonicity over the specified temperature range.

Feature Summary

• Dual 10-bit DACs with integrated 4.096V precision reference
• 10ppm/°C reference temperature coefficient
• Maximum INL error of ±1 LSB
• SPI/MICROWIRE compatible 3-wire serial interface

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 the production line. Confirm that the H-grade automotive temperature rating (-40°C to 125°C) aligns with the environmental constraints of the target application. Ensure the 4.5V minimum supply voltage requirement is met by the system power rails.

Selection Notes

Select this component when a dual-channel DAC with high accuracy (±1 LSB INL) and low drift is required. The HZ suffix indicates a power-on reset to zero-scale, which is critical for applications where downstream circuits must remain inactive during initialization. The H-series requires a minimum supply voltage of 4.5V, distinguishing it from the L-series which supports lower voltages down to 2.7V.

Part Context

This part belongs to the LTC2632 family of dual DACs available in 8-, 10-, and 12-bit resolutions. The HTS8 designation identifies the automotive grade (H), TSOT-23 package (TS8), and specific reset/reference configuration. Other variants in the family include different resolutions (e.g., LTC2632HTS8-HI12) and commercial grades (C-series).

Replacement Considerations

Direct pin-compatible substitutes within the same family include the LTC2632HTS8-HI10#TRPBF (mid-scale reset) or LTC2632HTS8-LZ10#TRPBF (lower voltage operation). Verify that the alternative part's power-on reset behavior and supply voltage range are compatible with the existing circuit design.
