LTC2634HUD-LMX12#TRPBF

Overview

The LTC2634HUD-LMX12#TRPBF 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 4.096V and operates on a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the -40°C to 125°C automotive temperature range, and communicates via a 50MHz SPI-compatible serial interface. This specific part number indicates a tape-and-reel packaging format.

Feature Summary

Quad 12-bit resolution with maximum integral nonlinearity error of ±2.5 LSB
Integrated 4.096V precision reference with 10ppm/°C drift
AEC-Q100 qualified for automotive applications (-40°C to 125°C)
SPI/MICROWIRE compatible 3-wire serial interface operating up to 50MHz

Applications

Automotive systems requiring high-precision analog control
Process control and industrial automation equipment
Automatic test equipment
Portable instrumentation

Procurement Notes

Verify that the #TRPBF suffix confirms the 2,500-unit tape and reel packaging configuration. Ensure the H-grade designation matches the required -40°C to 125°C automotive operating temperature range. Confirm the LMX12 suffix corresponds to the external reference mode power-on reset behavior at mid-scale.

Selection Notes

Select this component when four independent 12-bit channels are required in a compact QFN package. The H-grade variant necessitates a minimum 4.5V supply voltage due to the 4.096V internal reference. Verify system compatibility with the mid-scale power-on reset state inherent to the LMX suffix configuration.

Part Context

This part belongs to the LTC2634 family of quad DACs available in 8-, 10-, and 12-bit resolutions. The HUD suffix identifies the 16-lead 3mm × 3mm QFN package type. The LMX12 designation specifies the 12-bit resolution combined with mid-scale reset functionality in external reference mode.

Replacement Considerations

Direct replacements within the same package and pinout include other LTC2634 variants such as the LTC2634HUD-HMI12 or LTC2634HUD-LZ12, provided the power-on reset requirements align with the application design.
