LTC2632HTS8-HI10#TRMPBF

Overview

The LTC2632HTS8-HI10#TRMPBF 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 electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, a settling time of 4.1µs at 5V, and a typical supply current of 0.5mA at 5V. The part supports power-on reset to mid-scale in internal reference mode.

Feature Summary

• Dual 10-bit DACs with integrated 4.096V precision reference (10ppm/°C)
• Maximum INL error of ±1 LSB and guaranteed monotonic operation
• 3-wire SPI/MICROWIRE serial interface supporting clock rates up to 50MHz
• 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 #TRMPBF indicates a 500-piece tape and reel packaging configuration. Confirm that 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 the required 4.5V to 5.5V supply range for the HI series.

Selection Notes

Select this component when a dual-channel DAC with high accuracy (±1 LSB INL) and low drift is required. The HI suffix specifies a 4.096V full-scale output, necessitating a minimum supply voltage of 4.5V. Choose the I suffix for mid-scale power-on reset or Z suffix for zero-scale reset depending on system initialization requirements. Verify that the 10-bit resolution meets the application's precision needs compared to 8-bit or 12-bit variants.

Part Context

This part belongs to the LTC2632 family of dual voltage-output DACs. Variants are distinguished by resolution (8, 10, or 12 bits), full-scale voltage (2.5V for L series, 4.096V for H series), and power-on reset behavior (I, X, or Z). The HTS8 variant specifically denotes the automotive temperature grade and TSOT-23 packaging.

Replacement Considerations

Direct substitutes within the same family include LTC2632HTS8-LI10#TRMPBF (2.5V FS, 2.7V-5.5V supply) or LTC2632HTS8-HZ10#TRMPBF (zero-scale reset). Cross-family replacements require matching pinout, resolution, and interface compatibility.
