LTC2633CTS8-HI12#TRPBF

Overview

The LTC2633CTS8-HI12#TRPBF is a dual-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It integrates high-accuracy, low-drift references with a temperature coefficient of 10ppm/°C. The device operates on a single supply ranging from 4.5V to 5.5V, providing a full-scale output of 4.096V. Communication is handled 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 ±1.5 LSB, rail-to-rail output buffers, and guaranteed monotonicity over the operating temperature range.

Feature Summary

• Dual 12-bit DACs with integrated precision reference (4.096V full-scale)
• Maximum INL error of ±1.5 LSB for high accuracy
• Rail-to-rail output buffers with guaranteed monotonicity
• 2-wire I²C interface with selectable power-on reset states

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates a tape and reel packaging format containing 2,500 pieces. Confirm that the 'H' grade designation matches the required automotive temperature range of –40°C to 125°C. Ensure the 'I' power-on reset code aligns with system initialization requirements for mid-scale output in internal reference mode.

Selection Notes

Select this part when a dual-channel solution with high linearity (±1.5 LSB INL) is required. The 4.5V to 5.5V supply range is necessary for the 4.096V full-scale output configuration. Consider the H-grade temperature rating if operation beyond commercial limits is needed. Verify I²C address configuration via the CA0 pin if multiple devices are present on the bus.

Part Context

This component belongs to the LTC2633 family of dual DACs. Variants differ by resolution (8, 10, or 12 bits), full-scale voltage (2.5V or 4.096V), and power-on reset behavior. The CTS8 package denotes an 8-lead plastic TSOT-23 form factor suitable for space-constrained designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-model compatibility within the LTC2633 family requires verification of pinout, supply voltage ranges, and I²C register maps.
