LTC2311IMSE-16#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2311IMSE-16#TRPBF is a 16-bit, 5Msps successive approximation register (SAR) analog-to-digital converter with differential inputs and a wide input common mode range. It operates from a single 3.3V or 5V supply, providing an 8V P-P differential input range. The device features a low drift internal reference (20ppm/°C max), SPI-compatible serial interface supporting CMOS or LVDS logic, and consumes 50mW at 5V. It guarantees 16-bit resolution with no missing codes and achieves typical SNR of 81dB.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the IMSE suffix corresponds to the industrial temperature grade (-40°C to 85°C). Ensure the MSOP-16 package dimensions match the PCB footprint requirements. Check for RoHS compliance status in the latest manufacturer documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring high throughput with minimal latency. The wide common mode range simplifies front-end signal conditioning by allowing direct connection to various signal types without complex biasing. Compare power consumption in nap and sleep modes against system idle requirements. Ensure the host interface supports the required CMOS or LVDS voltage levels defined by OVDD.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2311-16 family, which includes variants with different temperature grades and packaging options. The IMSE designation specifies the industrial temperature range and MSOP package. Other family members include CMSE (commercial) and HMSE (automotive/high-temp) variants, all sharing the same core ADC architecture and pinout.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same series include LTC2311CMSE-16#TRPBF (commercial temp) and LTC2311HMSE-16#TRPBF (high temp). Verify that the substitute part meets the specific operating temperature range requirements of the application environment.
