LTC2634IMSE-HMI10#TRPBF

Overview

The LTC2634IMSE-HMI10#TRPBF is a quad 10-bit voltage output digital-to-analog converter (DAC) in a 10-lead MSOP package. It features an integrated precision reference providing a 4.096V full-scale output, operating from 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 guaranteed monotonicity over the industrial temperature range of –40°C to 85°C. Power-on reset defaults to mid-scale in internal reference mode.

Feature Summary

• Quad 10-bit DACs with integrated 4.096V precision reference
• SPI/MICROWIRE compatible 3-wire serial interface (up to 50MHz)
• Rail-to-rail output buffers with ±1 LSB maximum INL error
• Power-on reset to mid-scale in internal reference mode

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging containing 2,500 pieces. Confirm the H-grade designation aligns with the required 4.5V to 5.5V supply range and 4.096V full-scale output specification for the target application environment.

Selection Notes

Select this part when a quad channel configuration with high accuracy (±1 LSB INL) and low power consumption is required. Ensure the system supply voltage remains within the 4.5V to 5.5V range, as lower voltages are not supported by the H-grade variant. Consider the MSE package size constraints against available PCB real estate.

Part Context

This component belongs to the LTC2634 family, which offers 12-, 10-, and 8-bit resolutions in both QFN and MSOP packages. The IMSE suffix identifies the Industrial temperature grade (-40°C to 85°C) and MSOP-10 package. The HMI10 designation specifies the 4.096V full-scale internal reference and mid-scale power-on reset behavior.

Replacement Considerations

Direct substitutes within the same family include LTC2634IMSE-HMX10#TRPBF (external reference mode) or LTC2634IMSE-HZ10#TRPBF (zero-scale reset). For different resolutions, consider LTC2634IMSE-HMI12#TRPBF or LTC2634IMSE-HMI8#TRPBF, ensuring pin compatibility and electrical parameter alignment.
