LTC2633HTS8-LI10

Overview

The LTC2633HTS8-LI10 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 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single 2.7V to 5.5V supply and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, rail-to-rail output buffers, and guaranteed monotonicity over the –40°C to 125°C temperature range. Power-on reset defaults to mid-scale in internal reference mode.

Feature Summary

• Dual 10-bit DACs with integrated 2.5V precision reference (10ppm/°C drift)
• I²C interface with selectable standard (100kHz) or fast (400kHz) clock rates
• Rail-to-rail output buffers with ±1 LSB maximum INL error
• Power-on reset configured for mid-scale output in internal reference mode

Applications

• Mobile communications systems
• Process control and industrial automation
• Portable equipment requiring low power consumption
• Automotive sensor interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm lead time and availability status. Ensure the selected temperature grade matches the operational environment requirements. Confirm that the I²C address configuration via the CA0 pin aligns with the system bus topology to prevent communication conflicts.

Selection Notes

Select this component when a dual-channel DAC with high accuracy (±1 LSB INL) and low power consumption is required in a compact TSOT-23 package. The LTC2633HTS8-LI10 is suitable for applications needing a 2.5V full-scale range and operation across the automotive temperature range (-40°C to 125°C). Consider external reference options if a different full-scale voltage is needed.

Part Context

This part belongs to the LTC2633 family of dual DACs, which offers various resolution options (8-, 10-, and 12-bit) and accuracy grades. The 'H' designation indicates the automotive temperature grade (-40°C to 125°C), while 'I10' specifies the 10-bit resolution with mid-scale power-on reset in internal reference mode. The 'TS8' denotes the 8-lead ThinSOT package type.

Replacement Considerations

Direct replacements within the same family include LTC2633HTS8-HI10 (4.096V full-scale) or LTC2633CT S8-LI10 (commercial temperature grade). Verify pin compatibility and software register mapping when substituting between different resolution or accuracy variants.
