LTC2345IUK-16#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2345IUK-16#TRPBF is an octal, 16-bit, 200ksps simultaneous sampling successive approximation register (SAR) analog-to-digital converter. It features differential inputs with a wide common mode range and SoftSpan technology for per-channel input range configuration. The device operates from a 5V supply and includes an internal reference and buffer. It supports pin-selectable SPI CMOS or LVDS serial interfaces. Key electrical specifications include ±1.25LSB maximum INL, guaranteed 16-bit no missing codes, 91dB typical SNR, and 81mW typical power dissipation.

Analog To Digital Converters (ADC) Procurement Notes

Verify the I suffix indicates the industrial temperature range of –40°C to 85°C. Confirm the #TRPBF suffix denotes tape and reel packaging. Ensure the specific grade matches system thermal requirements, as C and H grades offer different operating ranges.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight channels of simultaneous sampling are required. The SoftSpan feature allows independent configuration of input ranges per conversion cycle. Verify that the OVDD supply voltage aligns with the chosen digital interface mode, supporting 1.71V to 5.25V for CMOS and 2.375V to 5.25V for LVDS.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2345-16 family, which provides 16-bit precision ADCs in a 48-lead QFN package. The IUK variant specifies the industrial temperature grade. Other variants include the CUK (commercial) and HUK (high temperature) grades, sharing identical electrical performance but differing in operating temperature limits.
