LTC2633HTS8-LI10#TRPBF

Overview

The LTC2633HTS8-LI10#TRPBF is a dual-channel, 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates a precision internal reference with a temperature coefficient of ±10ppm/°C and operates on a single supply voltage ranging from 2.7V to 5.5V. The device features rail-to-rail output buffers 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, a typical supply current of 0.4mA at 3V, and guaranteed monotonicity over the –40°C to 125°C automotive temperature range.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF corresponds to the 2,500-piece tape and reel packaging format as defined in the manufacturer's documentation. Confirm that the LI10 designation correctly specifies the 10-bit resolution, internal reference mode, and mid-scale power-on reset behavior for the intended application requirements.

Selection Notes

Select this component when a dual-channel DAC with high accuracy (±1 LSB INL) and low power consumption (0.4mA) is required within a compact 8-lead TSOT-23 package. Ensure the system supply voltage falls within the 2.7V to 5.5V range compatible with the 'L' grade full-scale output. Verify that the I²C address configuration via the CA0 pin aligns with the bus topology constraints.

Part Context

This part belongs to the LTC2633 family of dual DACs, which offers various combinations of resolution (8-, 10-, or 12-bit), accuracy grades ('A' vs standard), and power-on reset options. The 'H' suffix indicates the automotive temperature grade (-40°C to 125°C), while 'TS8' denotes the 8-lead ThinSOT package type. The 'LI10' code specifically identifies the 10-bit resolution with internal reference and mid-scale reset functionality.

Replacement Considerations

Direct replacements within the same family include LTC2633HTS8-LI12#TRPBF for higher 12-bit resolution or LTC2633HTS8-LZ10#TRPBF if zero-scale power-on reset is preferred. Cross-family alternatives such as the LTC2635 offer quad channels but require different packaging and pinout considerations.
