LTC2635CMSE-HZ12#PBF

Overview

The LTC2635CMSE-HZ12#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 and operates from a single 4.5V to 5.5V supply. The device includes rail-to-rail output buffers, guaranteed monotonicity over the –40°C to 125°C automotive temperature range, and communicates via a 2-wire I²C-compatible serial interface supporting standard (100kHz) and fast (400kHz) modes.

Feature Summary

• Quad 12-bit resolution with maximum INL error of ±2.5 LSB
• Integrated 4.096V full-scale reference with 10ppm/°C drift
• Power-on reset to zero-scale in internal reference mode
• Ultralow crosstalk between DACs (3nV•s)

Applications

• Process control and industrial automation
• Portable equipment
• Automotive systems

Procurement Notes

Verify the MSE package designation and H-grade automotive temperature rating against the specific application requirements. Confirm that the power-on reset behavior aligns with system startup needs, as this variant resets to zero-scale.

Selection Notes

Select this part for applications requiring four independent 12-bit outputs with high accuracy in a compact surface-mount package. Ensure the supply voltage remains within the 4.5V to 5.5V range required for the H-grade internal reference operation.

Part Context

This component belongs to the LTC2635 family, which offers 12-, 10-, and 8-bit resolutions. The 'H' suffix indicates the 4.096V full-scale version, while 'MSE' specifies the 10-lead MSOP package. The '#PBF' suffix denotes a lead-free manufacturing process.

Replacement Considerations

Other members of the LTC2635 family, such as the LTC2635HMSE-HZ12 or LTC2635CMSE-HZ12, offer similar functionality with different temperature grades or reset behaviors. Verify pin compatibility and electrical specifications before substitution.
