LTC2634CUD-HMX10#TRPBF

Overview

The LTC2634CUD-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 utilizes a 3-wire SPI/MICROWIRE compatible interface with clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity error of ±1 LSB, rail-to-rail output buffers, and power-on reset to mid-scale in external reference mode. It is housed in a 16-lead 3mm × 3mm QFN package and supports commercial temperature ranges.

Feature Summary

• Quad 10-bit DACs with integrated 4.096V precision reference
• SPI/MICROWIRE compatible 3-wire serial interface operating at 50MHz
• Rail-to-rail output buffers with guaranteed monotonicity
• 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 specific suffix #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the H-grade designation aligns with the required automotive temperature range (-40°C to 125°C). Ensure the MX suffix matches the design requirement for power-on reset to mid-scale when using an external reference source.

Selection Notes

Select this part for applications requiring four independent 10-bit outputs with high accuracy. The H-series variant is necessary if the system requires a 4.096V full-scale output or must operate within the -40°C to 125°C temperature range. Verify that the supply voltage remains between 4.5V and 5.5V to meet specified performance parameters.

Part Context

This component belongs to the LTC2634 family, which includes 8-bit, 10-bit, and 12-bit variants. The CUD package denotes the commercial temperature grade in a 16-lead QFN format. The H suffix specifies the 4.096V internal reference capability, while the MX suffix defines the specific power-on reset behavior for external reference configurations.

Replacement Considerations

Direct substitutes within the same family include LTC2634CUD-HMI10#TRPBF (internal reference reset) or LTC2634CUD-HZ10#TRPBF (zero-scale reset). For different resolutions, consider LTC2634CUD-HMX12#TRPBF or LTC2634CUD-HMX8#TRPBF.
