LTC2311HMSE-12#WTRPBF

Analog To Digital Converters (ADC) Overview

The LTC2311HMSE-12#WTRPBF is a 12-bit + sign successive approximation register (SAR) analog-to-digital converter featuring differential inputs and a wide input common mode range. It operates from a single 3.3V or 5V supply with an 8VP-P differential input range. The device achieves ±0.25LSB typical integral nonlinearity, no missing codes at 12 bits, and 73dB typical signal-to-noise ratio. It includes an onboard low drift reference and supports CMOS or LVDS SPI-compatible serial interfaces. This automotive-grade component operates within a temperature range of –40°C to 125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #W suffix indicates automotive grade manufacturing standards. Confirm the #TRPBF suffix denotes tape and reel packaging. Ensure the HMSE variant matches the required industrial temperature range of –40°C to 125°C. Cross-reference the specific lot traceability requirements for automotive reliability reports.

Analog To Digital Converters (ADC) Selection Notes

Select this part when automotive qualification and extended temperature operation are mandatory. The HMSE grade provides guaranteed performance up to 125°C compared to lower grades. Verify that the 5Msps throughput and 12-bit resolution meet system bandwidth and accuracy constraints. Ensure power supply rails align with the specified 3.3V or 5V operating conditions.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2311-12 family of high-speed SAR ADCs. It shares architectural similarities with commercial and industrial variants but differs in temperature grading and automotive reliability standards. The MSOP-16 package is consistent across the series, facilitating board layout reuse while accommodating different thermal and quality specifications.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2311IMSE-12#WTRPBF offers identical electrical performance but is rated for the industrial temperature range of –40°C to 85°C instead of the extended –40°C to 125°C range of the HMSE variant.
