LTC2636CMS-HZ10#TRPBF

Overview

The LTC2636CMS-HZ10#TRPBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated high-accuracy reference with a temperature coefficient of 10ppm/°C, providing a full-scale output of 4.096V. The device operates on a single supply voltage ranging from 4.5V to 5.5V and utilizes a 3-wire SPI/MICROWIRE-compatible serial interface with clock rates up to 50MHz. It includes double-buffered data latches, power-on reset to zero-scale, and rail-to-rail output buffers. The component is housed in a 14-lead DFN package and supports commercial operating temperatures from 0°C to 70°C.

Feature Summary

• Octal architecture with eight independent 10-bit DAC channels
• Integrated 10ppm/°C reference yielding 4.096V full-scale output
• Rail-to-rail output buffers with guaranteed monotonicity
• Power-on reset circuitry defaults outputs to zero-scale

Applications

• Process control and industrial automation systems
• Portable equipment requiring low power consumption
• Automotive electronic applications
• Optical networking infrastructure

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging containing 2500 pieces. Confirm the MSOP or DFN package variant matches the design requirements, as pinouts differ between packages. Ensure the C-grade temperature range aligns with the operational environment specifications.

Selection Notes

Select this part for designs requiring multiple synchronized analog outputs with precise internal referencing. The H-series designation ensures compatibility with 4.5V to 5.5V supply rails. Verify that the 50MHz serial clock speed meets the system's data throughput requirements and that the 14-lead DFN footprint fits the PCB layout constraints.

Part Context

This component belongs to the LTC2636 family of octal DACs, which also offers 8-bit and 12-bit resolutions. Variants within the family include L-series parts with 2.5V full-scale output and I/H-grade temperature options. The CMS-HZ10 configuration specifically targets commercial temperature ranges with zero-scale initialization.

Replacement Considerations

Direct substitutes within the same family include LTC2636CMS-LZ10#TRPBF for 2.5V operation or LTC2636CMS-HZ12#TRPBF for higher resolution. Cross-family replacements require verification of pin compatibility and reference voltage alignment.
