LTC2635CMSE-LMI10#TRPBF

Overview

The LTC2635CMSE-LMI10#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 supply ranging from 2.7V to 5.5V and utilizes a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity (INL) error of ±1 LSB, low noise of 0.75mVP-P (0.1Hz to 200kHz), and rail-to-rail output buffers that are guaranteed monotonic over the commercial temperature range of 0°C to 70°C.

Feature Summary

• Quad 10-bit resolution with integrated 2.5V precision reference
• 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)

Applications

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

Procurement Notes

Verify the package type corresponds to the 10-lead MSOP (MSE) designation within the part number. Confirm the suffix 'LMI10' indicates the specific power-on reset behavior for mid-scale initialization. Ensure the operating environment remains within the commercial temperature limits of 0°C to 70°C as specified for the C-grade variant.

Selection Notes

Select this component when four independent 10-bit DAC channels are required in a compact surface-mount package. The internal 2.5V reference simplifies design by eliminating external reference components. Consider the H-grade variants if automotive temperature ranges (-40°C to 125°C) or higher 4.096V full-scale outputs are necessary.

Part Context

This part belongs to the LTC2635 family, which includes 8-bit, 10-bit, and 12-bit resolutions. The CMSE prefix denotes the Commercial temperature grade and 10-lead MSOP package. Other variants in the series offer different reset behaviors (Zero-Scale, High-Impedance) and full-scale voltages (2.5V or 4.096V).

Replacement Considerations

Direct replacements within the same family include LTC2635CMSE-LZ10#TRPBF (Zero-Scale reset) or LTC2635CMSE-LMO10#TRPBF (High-Impedance reset). For wider temperature ranges, consider the H-grade equivalents such as LTC2635HMSE-LMI10#TRPBF.
