LTC2635CMSE-HMI10#TRPBF

Overview

The LTC2635CMSE-HMI10#TRPBF is a quad 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices, housed in a 10-lead MSOP package. 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 supply ranging from 2.7V to 5.5V and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical characteristics include rail-to-rail output buffers, guaranteed monotonicity over the operating range, and a maximum integral nonlinearity (INL) error of ±1 LSB.

Feature Summary

• Quad 10-bit resolution with integrated 2.5V precision reference (10ppm/°C drift)
• I²C-compatible serial interface with selectable slave addresses via CA0-CA2 pins
• Power-on reset configured to mid-scale in internal reference mode
• Rail-to-rail output buffers with ultralow crosstalk (3nV·s typical)

Applications

• Mobile communications systems
• Process control and industrial automation
• Portable equipment requiring low power consumption

Procurement Notes

Verify the specific ordering suffix HMI10 confirms the mid-scale power-on reset behavior for internal reference operation. Confirm the MSE package designation matches the required 10-lead MSOP footprint. Ensure the C-grade temperature rating (0°C to 70°C) aligns with the target application environment, as opposed to the H-grade automotive range.

Selection Notes

Select this component when a quad-channel DAC with I²C connectivity and moderate accuracy (±1 LSB INL) is required. The 2.5V full-scale output suits single-supply applications operating between 2.7V and 5.5V. Consider the external reference option if a different full-scale voltage is needed, or if system-level calibration requires an external reference source instead of the integrated one.

Part Context

This part belongs to the LTC2635 family, which includes 8-bit, 10-bit, and 12-bit variants. The CMSE suffix indicates the commercial temperature grade and MSOP package. Other packages include the 16-pin QFN (UD). Variants differ by resolution, full-scale voltage (L for 2.5V, H for 4.096V), and power-on reset state (Z for zero-scale, MI for mid-scale internal, MX for mid-scale external).

Replacement Considerations

Direct pin-compatible replacements within the same family include LTC2635CMSE-LMI10#TRPBF (zero-scale reset) or LTC2635CMSE-HMI10#TRPBF (automotive grade, 4.096V FS). Verify that the reset state and supply voltage requirements match the existing design constraints before substitution.
