LTC2633CTS8-LZ10#TRMPBF

Overview

The LTC2633CTS8-LZ10#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 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 2.7V to 5.5V 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 operating temperature range.

Feature Summary

• Dual 10-bit DACs with integrated 2.5V precision reference (10ppm/°C drift)
• I²C interface with selectable power-on reset to zero-scale
• Rail-to-rail output buffers with ±1 LSB maximum INL error
• Single 2.7V to 5.5V supply operation

Applications

• Mobile communications
• Process control and industrial automation
• Power supply margining
• Portable equipment
• Automotive systems

Procurement Notes

Verify the specific ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration, distinct from the standard 2,500-unit reel. Confirm that the 'C' temperature grade designation aligns with commercial operating requirements (0°C to 70°C), as automotive applications may require the 'H' grade variant (-40°C to 125°C). Ensure lead-free compliance matches project specifications.

Selection Notes

Select this part for applications requiring dual low-power DAC channels in a compact TSOT-23 footprint. The LZ10 suffix specifies a 10-bit resolution with a 2.5V internal reference and zero-scale power-on reset behavior. If mid-scale reset or external reference capability is required, consider alternative suffixes such as LI10 or LX10. Verify that the 2.7V minimum supply voltage meets the system's lowest operating condition.

Part Context

This component belongs to the LTC2633 family, which offers various combinations of resolution (8-, 10-, or 12-bit), accuracy grades, and power-on reset options. The LTS8 package denotes the 8-lead ThinSOT form factor. The 'A' electrical grade is absent from this specific part number, indicating it falls under the standard performance specifications rather than the tighter ±1.5LSB INL guarantee provided for the A-grade variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pin compatibility and electrical parameter overlaps if considering cross-references from other manufacturers.
