LTC2633CTS8-HI10#TRPBF

Overview

The LTC2633CTS8-HI10#TRPBF 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 4.096V and operates on a single 4.5V to 5.5V supply. The device communicates via 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.

Feature Summary

• Dual 10-bit DACs with integrated 4.096V precision reference
• I²C interface with selectable power-on reset to mid-scale
• Rail-to-rail output buffers with ±1 LSB maximum INL error
• Operating temperature range: –40°C to +125°C

Applications

• Process control and industrial automation systems
• Portable equipment requiring low power consumption
• Automotive electronic applications
• Power supply margining circuits

Procurement Notes

Verify the specific ordering suffix #TRPBF confirms the tape and reel packaging quantity of 2,500 pieces. Confirm the 'H' grade designation matches the required automotive temperature range of –40°C to +125°C for the application environment. Ensure the I²C address configuration via the CA0 pin aligns with the system bus requirements.

Selection Notes

Select this part when a dual-channel DAC with high accuracy (±1 LSB INL) and an internal 4.096V reference is required in a compact TSOT-23 package. The H-grade variant is necessary for environments exceeding 70°C. Verify that the supply voltage remains within the 4.5V to 5.5V range specified for the H-series devices to ensure proper operation of the internal reference and output drivers.

Part Context

This component belongs to the LTC2633 family of dual DACs, which offers various resolution options (8-, 10-, and 12-bit) and power-on reset configurations. The HI10 designation specifically indicates a 10-bit resolution with an internal 4.096V reference and mid-scale power-on reset behavior. It serves as a compact solution for applications needing precise analog voltage generation with minimal external component count.

Replacement Considerations

Direct replacements within the same family include LTC2633CTS8-HI12#TRPBF for higher 12-bit resolution or LTC2633CTS8-HZ10#TRPBF if zero-scale power-on reset is preferred instead of mid-scale. Ensure any substitute maintains the H-grade temperature rating and compatible I²C addressing.
