LTC2637CMS-HZ10#PBF

Digital To Analog Converters Overview

The LTC2637CMS-HZ10#PBF is an octal 10-bit voltage-output digital-to-analog converter featuring an integrated precision reference with a 10ppm/°C temperature coefficient. It operates from a single 4.5V to 5.5V supply, providing a full-scale output of 4.096V. The device includes rail-to-rail output buffers and guarantees monotonicity over the specified temperature range. Communication is handled via a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Upon power-up, the internal registers reset to zero-scale in internal reference mode.

• Optical networking devices

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix CMS-HZ10 against the manufacturer's current product selection guide to confirm package type, temperature grade, and reset configuration. Ensure the design supports the required 4.5V to 5.5V supply voltage for the H-grade variant. Confirm I2C address pin configurations match the system requirements before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when eight independent 10-bit voltage outputs are required within a compact footprint. The H-grade designation indicates operation from 4.5V to 5.5V with a 4.096V full-scale range. The Z suffix specifies a power-on reset to zero-scale, which is critical for applications requiring a known safe state upon initialization. Compare settling time and noise specifications against system bandwidth requirements.

Digital To Analog Converters Part Context

This part belongs to the LTC2637 family of octal DACs, available in 8-, 10-, and 12-bit resolutions. The family shares common architectural features including low crosstalk and double-buffered data latches. Variants differ by resolution, full-scale voltage (L vs H grades), package (DFN vs MSOP), and power-on reset behavior. The CMS-HZ10 specifically denotes the commercial temperature grade, MSOP package, and zero-scale reset configuration.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other LTC2637 variants with matching resolution and package, such as LTC2637CMS-HZ8#PBF or LTC2637CMS-HZ12#PBF, provided the reset behavior and temperature grade align with system needs. Cross-family replacements require verification of pin compatibility and electrical performance margins.
