LTC2311IMSE-14#WTRPBF

Analog To Digital Converters (ADC) Overview

The LTC2311IMSE-14#WTRPBF is a 14-bit successive approximation register (SAR) analog-to-digital converter with differential inputs and a wide common mode range. It operates from a single 3.3V or 5V supply, achieving a sampling rate of 5Msps with one-cycle latency. The device features an internal low-drift reference (20ppm/°C max), ±0.75LSB typical INL, and 80dB typical SNR at 2.2MHz input frequency. It supports CMOS or LVDS SPI-compatible serial interfaces and includes nap and sleep modes for power reduction.

Analog To Digital Converters (ADC) Feature Summary

• Differential input architecture with wide common mode range supporting arbitrary signal types without configuration
• Integrated temperature-compensated voltage reference with external buffer input capability
• Configurable high-speed serial interface compatible with both CMOS and LVDS logic levels
• Automotive-grade qualification ensuring reliability under extended temperature conditions

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems
• Automotive sensor interfaces
• Multiphase motor control
• Remote data acquisition networks

Analog To Digital Converters (ADC) Procurement Notes

Verify the #W suffix indicates automotive grade manufacturing standards. Confirm the IMSE designation specifies the industrial temperature range of –40°C to 85°C. Ensure the TRPBF suffix matches the required tape and reel packaging format for automated assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit resolution with 5Msps throughput is required in a small MSOP package. The wide input common mode range simplifies front-end signal conditioning design. Verify that the host system supports either CMOS or LVDS digital interfaces for optimal performance integration.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2311 family of SAR ADCs, which also includes 12-bit and 16-bit variants. The IMSE variant specifically denotes the industrial temperature grade within the plastic MSOP package lineup. It serves as a bridge between lower-resolution general-purpose converters and higher-precision slower devices.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2311IMSE-14#PBF offers identical electrical specifications but utilizes tube packaging instead of tape and reel.
