LTC2632HTS8-HI10#TRPBF

Overview

The LTC2632HTS8-HI10#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 with clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity (INL) error of ±2.5LSB, 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
• SPI/MICROWIRE compatible 3-wire serial interface operating up to 50MHz
• Maximum INL error of ±2.5LSB with guaranteed monotonicity
• Power-on reset to mid-scale in internal reference mode

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm that the HI designation requires a supply voltage between 4.5V and 5.5V. Ensure the HTS8 package type matches the target PCB footprint requirements for the 8-lead TSOT-23 configuration.

Selection Notes

Select this component when a dual-channel DAC with a fixed 4.096V full-scale range is required. The HI suffix specifies operation within the 4.5V to 5.5V supply window. Choose the I suffix for power-on reset to mid-scale or Z for zero-scale depending on system initialization needs. Verify that the 10-bit resolution meets the application's accuracy constraints relative to the ±2.5LSB INL specification.

Part Context

This part belongs to the LTC2632 family of dual DACs available in 8-, 10-, and 12-bit resolutions. Variants are distinguished by their full-scale voltage (2.5V for L series, 4.096V for H series) and power-on reset behavior. The HTS8 suffix denotes the automotive-grade temperature range (-40°C to 125°C) and the TSOT-23 package style.

Replacement Considerations

Direct substitutes within the same family include LTC2632HTS8-HI12#TRPBF for higher resolution or LTC2632HTS8-LI10#TRPBF if a lower supply voltage range is acceptable. Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
