LTC2636CMS-HMX10#PBF

Overview

The LTC2636CMS-HMX10#PBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a 16-lead MSOP package and operates within a supply voltage range of 4.5V to 5.5V. The device includes an integrated precision reference with a temperature coefficient of 10ppm/°C, setting the full-scale output to 4.096V. It utilizes a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key electrical characteristics include a maximum integral nonlinearity error of ±1 LSB, a settling time of 4.3µs at 5V, and a typical supply current of 1.1mA. The part guarantees monotonicity over the operating temperature range.

Feature Summary

• Octal architecture providing eight independent 10-bit DAC channels in a single 16-lead MSOP package
• Integrated 10ppm/°C precision reference establishing a 4.096V full-scale output voltage
• Power-on reset configured for mid-scale output when using external reference mode (suffix MX)
• Rail-to-rail output buffers with ultralow crosstalk between DACs (<2.4nV•s)

Applications

• Process control and industrial automation systems requiring multi-channel signal generation
• Automatic test equipment utilizing precise voltage references
• Portable battery-powered instrumentation

Procurement Notes

Verify the specific ordering suffix HMX10#PBF against the manufacturer's datasheet to confirm the 16-lead MSOP package, 4.096V full-scale range, and external reference power-on reset behavior. Ensure the application supply voltage remains within the 4.5V to 5.5V specification required for the H-grade internal reference operation.

Selection Notes

Select this component when eight isolated voltage outputs are required in a compact surface-mount footprint. The H-grade designation indicates suitability for automotive or high-temperature environments (-40°C to 125°C). Choose the MX suffix if the system requires outputs to settle at mid-scale upon power-up while utilizing an external reference voltage source.

Part Context

This part belongs to the LTC2636 family of octal DACs, which also offers 8-bit and 12-bit resolution variants. The CMS designation identifies the commercial temperature grade (0°C to 70°C), while the H suffix in the resolution/power section denotes the 4.096V full-scale capability requiring a higher supply voltage than the L-series parts.

Replacement Considerations

Direct pin-compatible replacements within the same package include other LTC2636 variants such as LTC2636CMS-LMX10#PBF (2.5V full-scale) or LTC2636CMS-HMI10#PBF (internal reference power-on reset). Verify that the replacement matches the required full-scale voltage and power-on state configuration.
