LTC2635CMSE-LMO10#PBF

Digital To Analog Converters Overview

The LTC2635CMSE-LMO10#PBF 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 operates on a single 2.7V to 5.5V supply. The device includes rail-to-rail output buffers and guarantees monotonicity over the operating temperature range. Communication is handled via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. A key feature is the power-on reset configuration that sets outputs to a high-impedance state upon initialization.

Digital To Analog Converters Feature Summary

• Quad 10-bit resolution with integrated 2.5V precision reference
• Power-on reset to High-Impedance state for safe startup
• Rail-to-rail output buffers with guaranteed monotonicity
• I²C interface with selectable slave addresses via CA0/CA1 pins

Digital To Analog Converters Applications

• Process control and industrial automation systems
• Portable battery-powered equipment
• Automotive electronic modules
• Mobile communications infrastructure

Digital To Analog Converters Procurement Notes

Verify the specific LMO suffix indicates the High-Impedance power-on reset option. Confirm the MSE package designation matches the required 10-lead MSOP footprint. Ensure the C grade commercial temperature rating meets the operational environment requirements. Check RoHS compliance status if mandated by local regulations.

Digital To Analog Converters Selection Notes

Select this part when a quad DAC with I²C connectivity and safe high-impedance startup is required. The LMO suffix is distinct from LZ (zero-scale) or LMI (mid-scale) options. Consider the 2.7V minimum supply voltage for low-power applications. Verify that the 10-bit resolution and 2.5V full-scale range suit the system's dynamic range needs.

Digital To Analog Converters Part Context

This component belongs to the LTC2635 family of quad DACs, which also includes 8-bit and 12-bit variants. The family shares similar architectures but differs in resolution, noise performance, and full-scale voltage options (L vs H grades). The CMSE designation specifies the commercial temperature grade and MSOP packaging, distinguishing it from the automotive H-grade or QFN package versions.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include LTC2635CMSE-LZ10#PBF or LTC2635CMSE-LMI10#PBF, provided the different power-on reset behavior is acceptable. Other families like LTC2634 require SPI interfaces and are not pin-compatible.
