LTC2637HMS-HZ10#PBF

Overview

The LTC2637HMS-HZ10#PBF is an octal 10-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a 4.096V full-scale output and operates on a 4.5V to 5.5V supply. The device utilizes a 2-wire I2C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes. Key electrical specifications include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 4.3µs at ±1 LSB, and ultralow DAC-to-DAC crosstalk of 3nV•s. It is housed in a 16-lead MSOP package and guarantees monotonicity over the –40°C to 125°C temperature range.

Feature Summary

• Octal 10-bit resolution with rail-to-rail output buffers
• Integrated 4.096V precision reference with 10ppm/°C drift
• Ultralow crosstalk between DAC channels (<3nV•s)
• Power-on reset configured to zero-scale in internal reference mode

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment
• Automotive systems
• Optical networking

Procurement Notes

Verify the specific ordering suffix HZ10 against official documentation to confirm the hardware revision, power-on reset behavior (zero-scale), and 10-bit resolution. Ensure the procurement channel provides genuine Analog Devices components to guarantee performance within the specified –40°C to 125°C operating range and electrical characteristics.

Selection Notes

Select this component for applications requiring multiple low-drift voltage outputs with minimal inter-channel interference. The H-grade variant supports automotive temperature ranges up to 125°C. Verify that the system supply voltage remains within the 4.5V to 5.5V range required for the 4.096V full-scale output configuration.

Part Context

This part belongs to the LTC2637 family of octal DACs, which also includes 8-bit and 12-bit variants. The 'H' designation indicates the automotive temperature grade (–40°C to 125°C) and 4.096V internal reference. The 'Z' suffix specifies a power-on reset to zero-scale, while 'MS' denotes the 16-lead MSOP package.

Replacement Considerations

Direct replacements within the same family include LTC2637HMS-HZ12#PBF (12-bit) or LTC2637HMS-HZ8#PBF (8-bit). For different reset behaviors, consider LTC2637HMS-HMI10#PBF (mid-scale reset). Cross-family SPI-based alternatives like the LTC2636 series require interface adaptation.
