LTC2634IUD-LMI10#TRPBF

Overview

The LTC2634IUD-LMI10#TRPBF is a quad 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 includes rail-to-rail output buffers, guaranteed monotonicity over the -40°C to 85°C industrial temperature range, and a power-on reset to mid-scale in internal reference mode. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. It is housed in a 16-lead 3mm × 3mm QFN package.

Feature Summary

• Quad 10-bit resolution with ±1 LSB maximum INL error
• Integrated 10ppm/°C precision reference providing 2.5V full-scale output
• Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s)
• Power-on reset to mid-scale in internal reference mode

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the I-grade designation matches the required -40°C to 85°C operating temperature range for the target application environment.

Selection Notes

Select this part for applications requiring four independent 10-bit channels with low drift. Ensure the system supply voltage remains within 2.7V to 5.5V. If external reference capability or different power-on reset states are needed, consider other variants within the LTC2634 family.

Part Context

This component belongs to the LTC2634 family of quad DACs available in 12-, 10-, and 8-bit resolutions. The 'I' denotes the industrial temperature grade, while 'UD' specifies the 16-lead QFN package. The 'LMI10' configuration sets the full-scale voltage to 2.5V with internal reference and mid-scale power-on reset.

Replacement Considerations

Direct replacements include other LTC2634 variants with matching resolution and package, such as LTC2634IUD-LMX10#TRPBF for external reference operation, or LTC2634IUD-HMI10#TRPBF for 4.096V full-scale output.
