LTC2391CUK-16#TRPBF

Overview

The LTC2391CUK-16#TRPBF is a low noise, high speed 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 5V supply and supports a ±4.096V fully differential input range. The device achieves a typical SNR of 94dB at 250ksps throughput with no cycle latency in both parallel and serial interface modes. Key electrical parameters include a maximum INL of ±2LSB, guaranteed 16-bit no missing codes, and 95mW power dissipation at full sampling rate. It features an internal precision reference with ±20ppm/°C max temperature coefficient.

Feature Summary

16-bit resolution with 250ksps throughput and no pipeline delay
94dB typical SNR and 104dB SFDR at fIN = 20kHz
Internal precision reference with ±20ppm/°C max temperature coefficient
±4.096V fully differential input range on single 5V supply

Applications

Medical Imaging
High Speed Data Acquisition
Digital Signal Processing
Industrial Process Control
Instrumentation

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the C grade corresponds to the 0°C to 70°C operating temperature range. Ensure the QFN-48 package footprint matches the PCB design requirements. Check for RoHS compliance status as specified in the manufacturer documentation.

Selection Notes

Select this component when a 16-bit SAR ADC with low noise and high dynamic range is required. The internal reference simplifies design but external references may be needed for higher accuracy. Consider the 95mW power consumption at 250ksps for thermal management. Verify that the 1.8V to 5V I/O voltage compatibility matches the system logic levels.

Part Context

This part belongs to the LTC2391-16 family of low noise, high speed SAR ADCs. It shares architectural similarities with the LTC2392-16 and LTC2393-16, which offer different throughput rates or interface options. The CUk designation specifies the commercial temperature grade and QFN package variant within this product line.
