LTC2632CTS8-LI10#TRPBF

Overview

The LTC2632CTS8-LI10#TRPBF 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 a temperature coefficient of 10ppm/°C. The device operates on a single supply voltage ranging from 2.7V to 5.5V. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface for communication, supporting clock rates up to 50MHz. The part includes rail-to-rail output buffers and is guaranteed monotonic. Upon power-up, the outputs reset to mid-scale in internal reference mode.

Feature Summary

• Dual 10-bit DACs with integrated 2.5V full-scale reference
• Low drift reference: 10ppm/°C temperature coefficient
• SPI/MICROWIRE compatible 3-wire serial interface
• Power-on reset to mid-scale in internal reference mode

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates a tape and reel quantity of 2,500 pieces. Confirm the package type TSOT-23 matches the design footprint requirements. Ensure the C-grade commercial temperature range (0°C to 70°C) aligns with the system operating environment specifications.

Selection Notes

Select this model for applications requiring dual channels with a 2.5V internal reference span. The 10-bit resolution offers a balance between accuracy and data throughput. Verify that the supply voltage remains within the 2.7V to 5.5V range. Consider the ±1LSB maximum INL specification for linearity-critical designs.

Part Context

This component belongs to the LTC2632 family, which includes 12-, 10-, and 8-bit variants. The 'LI' suffix denotes the 10-bit resolution with a 2.5V full-scale internal reference and mid-scale power-on reset. Other variants include LZ for zero-scale reset and H-series for 4.096V spans.

Replacement Considerations

Direct substitutes within the same family include LTC2632CTS8-LZ10#TRPBF for zero-scale reset or LTC2632CTS8-LI12#TRPBF for higher 12-bit resolution. Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
