LTC2634CUD-LMX12#PBF

Overview

The LTC2634CUD-LMX12#PBF is a quad 12-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 ranging from 2.7V to 5.5V and utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. It includes rail-to-rail output buffers, double-buffered data latches, and a power-on reset circuit configured to set outputs to mid-scale in external reference mode upon initialization.

Feature Summary

Quad 12-bit resolution with maximum integral nonlinearity error of ±2.5 LSB
Integrated 2.5V full-scale reference with 10ppm/°C drift
Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s)
Power-on reset to mid-scale in external reference mode

Applications

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

Procurement Notes

Verify the package type corresponds to the 16-lead QFN format indicated by the 'UD' suffix in the part number. Confirm that the operating environment supports the commercial temperature range specified for the 'C' grade variant. Ensure the system design accommodates the 2.7V to 5.5V supply requirements for proper functionality.

Selection Notes

Select this component when a quad-channel DAC with 12-bit accuracy and low noise is required. The LMX suffix indicates a specific power-on reset behavior suitable for applications where mid-scale initialization in external reference mode is preferred. Consider the H-grade variants if operation above 85°C or up to 125°C is necessary.

Part Context

This part belongs to the LTC2634 family, which offers 12-, 10-, and 8-bit resolutions in both QFN and MSOP packages. The CUD-LMX12 designation specifically identifies the commercial temperature grade, 16-lead QFN package, external reference mid-scale reset configuration, and 12-bit resolution within this product line.
