LTC2632HTS8-HI10

Overview

The LTC2632HTS8-HI10 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) 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 for high accuracy
• SPI/MICROWIRE compatible 3-wire serial interface
• Rail-to-rail output buffers with ±1 LSB max INL

Applications

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

Procurement Notes

Verify the specific ordering suffix HTS8 against official documentation to confirm package type and tape/reel configuration. Confirm that the HI designation aligns with the required 4.5V to 5.5V supply range and 4.096V full-scale output. Ensure the H grade meets the –40°C to 125°C automotive temperature requirements for the target application environment.

Selection Notes

Select this component when a dual-channel DAC with a fixed 4.096V internal reference is required. The HI suffix indicates mid-scale power-on reset behavior in internal reference mode. Compare against the LZ variant if zero-scale reset is preferred upon power-up. Ensure the system supply voltage remains within the 4.5V to 5.5V window for proper operation of the H-grade device.

Part Context

This part belongs to the LTC2632 family, which offers various resolutions (8-, 10-, and 12-bit) and reset configurations. The HI10 specifically denotes the 10-bit resolution variant with mid-scale reset and high-voltage reference capabilities. It shares the same physical footprint and interface as other members of the series, allowing for potential pin-compatible upgrades or downgrades in resolution depending on application needs.
