LTC2634IUD-HMX10#TRPBF

Overview

The LTC2634IUD-HMX10#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 85°C industrial temperature range, and a power-on reset to mid-scale in external reference mode. Communication is handled via a 50MHz SPI/MICROWIRE compatible 3-wire serial interface.

Feature Summary

• Quad 10-bit DACs with integrated 4.096V precision reference
• Rail-to-rail output buffers with ultralow crosstalk (2.4nV·s)
• SPI/MICROWIRE compatible 3-wire serial interface 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 systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the I-grade designation corresponds to the -40°C to 85°C operating temperature range. Ensure the H-series designation matches the required 4.5V to 5.5V supply voltage for the 4.096V full-scale output configuration.

Selection Notes

Select this part when a quad 10-bit DAC with a fixed 4.096V internal reference is required. The H-series variant necessitates a minimum supply voltage of 4.5V. The MX suffix specifies a power-on reset behavior that sets outputs to mid-scale when using an external reference, which differs from the MI suffix used for internal reference modes.

Part Context

This component belongs to the LTC2634 family of quad DACs available in 12-, 10-, and 8-bit resolutions. The IUD package identifies it as an industrial grade device in a 16-lead QFN form factor. The H suffix denotes the 4.096V full-scale capability, while the MX suffix defines the specific power-on reset logic for external reference applications.

Replacement Considerations

LTC2634IUD-LMX10#TRPBF: Identical specifications except for power-on reset behavior in internal reference mode.
