LTC2311IMSE-14#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2311IMSE-14#TRPBF is a 14-bit successive approximation register (SAR) analog-to-digital converter in a 16-lead MSOP package. It operates from a single 3.3V or 5V supply with a maximum sampling rate of 5Msps and one-cycle latency. The device features differential inputs with an 8Vp-p range and wide common-mode capability. Key electrical parameters include ±0.75LSB typical integral nonlinearity, 80dB typical SNR at 2.2MHz input, and 50mW power dissipation at 5V. It integrates a low-drift internal reference and supports CMOS or LVDS SPI-compatible serial interfaces.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging when sourcing this component. Confirm the IMSE designation corresponds to the industrial temperature range of –40°C to 85°C. Ensure compatibility with the required OVDD voltage levels for the selected CMOS or LVDS interface mode before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring high-speed conversion with minimal latency. The integrated reference simplifies design by reducing external component count. Choose between CMOS and LVDS outputs based on noise immunity requirements and host interface voltage levels. Verify that the 14-bit resolution meets the system's dynamic range needs compared to higher-resolution alternatives.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2311 family of SAR ADCs, which includes 12-bit, 14-bit, and 16-bit variants. The IMSE-14 variant specifically offers 14-bit resolution in a compact MSOP package. It shares pinouts and functionality with other members of the series, allowing for potential upgrades or downgrades in resolution without changing the PCB layout.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2311HMSE-14#TRPBF serves as a direct replacement for extended temperature ranges up to 125°C. The LTC2311CMSE-14#TRPBF is suitable for commercial temperature ranges only. Other members of the LTC2311 series may be considered if different resolution or sampling rates are acceptable.
