LTC2634CMSE-HMI12#PBF

Overview

The LTC2634CMSE-HMI12#PBF is a quad 12-bit voltage output digital-to-analog converter (DAC) in a 10-lead MSOP package. It features an integrated precision reference with a full-scale output of 4.096V, requiring a supply voltage between 4.5V and 5.5V. The device includes rail-to-rail output buffers, guaranteed monotonicity over the temperature range, and a power-on reset to mid-scale in internal reference mode. Communication is handled via a 3-wire SPI/MICROWIRE compatible interface operating at clock rates up to 50MHz.

Feature Summary

• Quad 12-bit resolution with ±2.5 LSB maximum integral nonlinearity error
• Integrated 4.096V full-scale reference with 10ppm/°C drift
• Power-on reset to mid-scale in internal reference mode
• Rail-to-rail output buffers with ultralow crosstalk (2.4nV•s)

Applications

• Mobile communications
• Process control and industrial automation
• Automatic test equipment
• Portable equipment

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence. Confirm the MSE package designation corresponds to the 10-lead MSOP form factor required for the design. Ensure the H-grade temperature rating (-40°C to 125°C) matches the operational environment specifications.

Selection Notes

Select this part when a 4.096V full-scale output is required with an internal reference. The H-grade variant supports operation from 4.5V to 5.5V supplies. Choose the MSE package for space-constrained designs needing a 10-lead footprint instead of the 16-lead QFN option.

Part Context

This component belongs to the LTC2634 family of quad DACs available in 12-, 10-, and 8-bit resolutions. The CMSE-HMI12 variant specifically denotes the Commercial temperature grade, MSOP package, High full-scale voltage (4.096V), Mid-scale reset, and 12-bit resolution configuration within the Analog Devices portfolio.

Replacement Considerations

Other members of the LTC2634 family, such as LTC2634IMSE-HMI12#PBF or LTC2634HUD-LMX12#PBF, offer similar functionality with variations in temperature grade, package type, or reset behavior. Verify pin compatibility and electrical specifications before substitution.
