LTC2634HUD-HMX10#PBF

Overview

The LTC2634HUD-HMX10#PBF 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 from a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers and is guaranteed monotonic over the –40°C to 125°C temperature range. Communication is handled via an SPI/MICROWIRE compatible 3-wire serial interface with clock rates up to 50MHz. This specific variant resets to mid-scale in external reference mode upon power-up.

Feature Summary

Quad 10-bit DACs with integrated 4.096V precision reference
Rail-to-rail output buffers guaranteed monotonic over –40°C to 125°C
SPI/MICROWIRE compatible 3-wire serial interface operating up to 50MHz
Power-on reset to mid-scale in external reference mode

Applications

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

Procurement Notes

Verify the part number suffix #PBF indicates lead-free construction and RoHS compliance. Confirm the H-grade designation corresponds to the automotive temperature range of –40°C to 125°C. Ensure the MUX suffix aligns with the required mid-scale reset behavior in external reference mode. Cross-reference the UD package code for the 16-lead QFN form factor.

Selection Notes

Select this component when a quad-channel DAC with high accuracy and wide temperature tolerance is required. The H-grade ensures operation up to 125°C, suitable for automotive environments. The HMX suffix specifies mid-scale reset in external reference mode; choose HMI if internal reference mid-scale reset is needed, or HZ for zero-scale reset. Verify supply voltage constraints between 4.5V and 5.5V.

Part Context

This part belongs to the LTC2634 family of quad 12-, 10-, and 8-bit rail-to-rail DACs. The family shares common architecture including integrated references and SPI interfaces but varies in resolution, full-scale voltage options (2.5V or 4.096V), and power-on reset configurations. The HUD package denotes the 16-lead QFN format used in this specific ordering code.
