LTC2633CTS8-HZ10#TRPBF

Overview

The LTC2633CTS8-HZ10#TRPBF is a dual 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, providing a full-scale output of 2.5V. The device operates on a single supply voltage ranging from 2.7V to 5.5V and features rail-to-rail output buffers that are guaranteed monotonic over the commercial temperature range of 0°C to 70°C. Communication is handled via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Upon power-up, the outputs reset to zero-scale.

Feature Summary

• Dual 10-bit resolution with integrated 2.5V precision reference (10ppm/°C)
• Rail-to-rail output buffers guaranteed monotonic from 0°C to 70°C
• I²C interface with selectable standard (100kHz) and fast (400kHz) clock rates
• Power-on reset function clears outputs to zero-scale

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm the C grade corresponds to the commercial temperature range (0°C to 70°C). Ensure the HZ code aligns with the required zero-scale power-on reset behavior for the system initialization sequence.

Selection Notes

Select this part when a dual-channel DAC with low pin count is required in an 8-lead TSOT-23 package. The 10-bit resolution offers a balance between accuracy and data throughput. Choose this variant over the -LZ12 or -HZ10 if the 2.5V full-scale range and commercial temperature rating meet the design constraints.

Part Context

This component belongs to the LTC2633 family, which includes 8-, 10-, and 12-bit variants. The 'C' denotes the commercial temperature grade, while 'H' would indicate the automotive grade (-40°C to 125°C). The 'Z' suffix specifies the zero-scale power-on reset option, distinct from 'I' (mid-scale internal) or 'X' (mid-scale external).

Replacement Considerations

Direct replacements within the same family include LTC2633CTS8-LZ10#TRPBF for 12-bit resolution or LTC2633HTS8-HZ10#TRPBF for extended temperature range. Verify that the replacement maintains the 2.5V full-scale output and zero-scale reset requirement.
