LTC2633CTS8-LO10#TRMPBF

Overview

The LTC2633CTS8-LO10#TRMPBF is a dual 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference with a full-scale output of 2.5V and operates on a single 2.7V to 5.5V supply. The device utilizes a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, rail-to-rail output buffers, and guaranteed monotonicity over the operating temperature range. This specific variant includes a power-on reset function that sets DAC outputs to a high-impedance state upon initialization.

Feature Summary

• Dual 10-bit resolution with rail-to-rail output buffers
• Integrated 2.5V full-scale precision reference (10ppm/°C drift)
• Power-on reset to High-Impedance state for safe startup
• I²C interface with selectable slave address via CA0 pin

Applications

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

Procurement Notes

Verify the ordering suffix #TRMPBF indicates a 500-unit tape and reel packaging configuration. Confirm the C-grade designation aligns with commercial temperature requirements (0°C to 70°C). Ensure the LO10 code corresponds to the 10-bit resolution and high-impedance power-on reset option specified in the manufacturer's selection guide.

Selection Notes

Select this component when a dual-channel DAC with 10-bit accuracy and low power consumption is required. The LO10 suffix is critical for applications needing high-impedance outputs at power-up to prevent downstream circuit interference. Verify that the system supply voltage falls within the 2.7V to 5.5V range compatible with the L-series internal reference.

Part Context

This part belongs to the LTC2633 family of dual DACs, which also includes 8-bit and 12-bit variants. The 'CTS8' identifier denotes the commercial temperature grade and 8-lead TSOT-23 package. The 'LO10' code specifies the 10-bit resolution and the unique high-impedance power-on reset behavior, distinguishing it from mid-scale or zero-scale reset options.

Replacement Considerations

Direct replacements within the same family include LTC2633CTS8-LI10#TRMPBF (mid-scale reset) or LTC2633CTS8-LZ10#TRMPBF (zero-scale reset), provided the power-on reset behavior difference is acceptable. For higher resolution, consider the 12-bit LTC2633A series, noting potential INL specification changes.
