LTC2311IMSE-12#WPBF

Analog To Digital Converters (ADC) Overview

The LTC2311IMSE-12#WPBF is a 12-bit successive approximation register (SAR) analog-to-digital converter featuring differential inputs and a wide common mode range. It operates from a single 3.3V or 5V supply with a maximum sampling rate of 5Msps. The device includes an internal low-drift reference (20ppm/°C max) and supports both CMOS and LVDS SPI-compatible serial interfaces. Key electrical parameters include ±0.25LSB typical INL, 73dB typical SNR at 2.2MHz input frequency, and 8VP-P differential input range. It is qualified for automotive applications and functions within a temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #W suffix indicates automotive grade compliance when sourcing. Confirm package type is MSOP-16. Check RoHS status against specific project requirements. Ensure operating temperature range matches system specifications. Validate pinout compatibility during integration planning.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring high speed and automotive reliability. Compare power consumption between CMOS and LVDS modes based on interface needs. Consider the internal reference drift if extreme precision is required over wide temperature ranges. Evaluate board space constraints due to the small MSOP package size.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2311 family of SAR ADCs. It shares architectural similarities with other variants in the series but differs in resolution and temperature rating. The #WPBF suffix denotes automotive qualification and lead-free packaging. It complements Linear Technology's portfolio of high-performance data converters.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2311IMSE-12#PBF offers identical electrical performance but lacks automotive qualification. LTC2311HMSE-12#WPBF provides an extended temperature range up to 125°C. Verify pin compatibility and software interface settings when substituting these variants.
