LTC2634CUD-HMI10#TRPBF

Overview

The LTC2634CUD-HMI10#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 2.5V and a temperature coefficient of 10ppm/°C. The device operates on a single 2.7V to 5.5V supply and includes rail-to-rail output buffers guaranteed monotonic over the commercial temperature range of 0°C to 70°C. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface supporting clock rates up to 50MHz. Key electrical parameters include a settling time of 3.8µs, maximum integral nonlinearity of ±1 LSB, and a typical supply current of 0.6mA at 3V.

Feature Summary

• Quad 10-bit DAC architecture with integrated 2.5V precision reference
• Rail-to-rail output buffers with guaranteed monotonicity
• SPI/MICROWIRE compatible 3-wire serial interface with 50MHz clock rate
• Power-on reset to mid-scale in internal reference mode

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment

Procurement Notes

Verify the #TRPBF suffix indicates a tape and reel packaging format containing 2,500 units. Confirm the C grade corresponds to the commercial operating temperature range of 0°C to 70°C. Ensure the HMI suffix matches the required power-on reset behavior for mid-scale initialization in internal reference mode.

Selection Notes

Select this component when a quad 10-bit resolution is required with an integrated 2.5V reference. The HMI suffix is critical if mid-scale power-on reset is necessary. For applications requiring a 4.096V full-scale output or external reference operation, consider the H-series variants instead.

Part Context

This part belongs to the LTC2634 family of quad DACs available in 12-, 10-, and 8-bit resolutions. It utilizes the 16-lead QFN package (UD) and is distinguished by its specific resolution, temperature grade, and power-on reset configuration within the broader product line.

Replacement Considerations

Direct substitutes within the same family include LTC2634CUD-LMI10#TRPBF for zero-scale reset or LTC2634CUD-HZ10#TRPBF for different reset behaviors. Cross-package alternatives like the MSOP version require pinout verification.
