LTC2634HUD-LMX10#TRPBF

Overview

The LTC2634HUD-LMX10#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 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/MICROWIRE compatible 3-wire serial interface. This specific part number indicates a QFN package, tape and reel packaging, and a power-on reset configuration that sets outputs to mid-scale when using an external reference.

Feature Summary

Quad 10-bit resolution with ±1 LSB maximum Integral Nonlinearity (INL)
Integrated 4.096V full-scale reference with 10ppm/°C drift
Automotive grade (-40°C to 125°C) with AEC-Q100 qualification
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 H suffix confirms the 4.5V minimum supply requirement for the 4.096V internal reference. Confirm the LMX suffix specifies the mid-scale reset behavior under external reference conditions. Ensure the TRPBF suffix matches the required tape and reel quantity and lead-free status for the manufacturing process.

Selection Notes

Select this component if a 4.096V full-scale range is required with a minimum 4.5V supply. The LMX suffix is critical for applications needing a mid-scale power-up state when driving an external reference. Compare settling time specifications against system update rates, noting the typical 4.2µs value at 5V.

Part Context

This part belongs to the LTC2634 family, which offers 8-, 10-, and 12-bit resolutions in both QFN and MSOP packages. The HUD designation identifies the high-temperature automotive grade variant. Other variants include the LTC2634HMI10 for internal reference mid-scale reset or the LTC2634HZ10 for zero-scale reset.
