LTC2389IUK-18#TRPBF

Overview

The LTC2389IUK-18#TRPBF is an 18-bit, 2.5Msps successive approximation register (SAR) analog-to-digital converter from Analog Devices Inc. It operates on a single 5V supply and features pin-configurable analog input ranges: ±4.096V fully differential, 0V to 4.096V pseudo-differential unipolar, and ±2.048V pseudo-differential bipolar. The device guarantees 18-bit resolution with no missing codes and achieves a maximum integral nonlinearity (INL) of ±3LSB. It includes a precision internal 4.096V reference with ±20ppm/°C temperature coefficient and dissipates 162.5mW at full speed.

Automated Test Equipment

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the I-grade designation corresponds to the –40°C to 85°C operating temperature range. Ensure the QFN package dimensions match the PCB footprint requirements.

Selection Notes

Select this part for applications requiring high-speed conversion with flexible input configurations. The internal reference simplifies design by reducing external component count. Consider the 162.5mW power dissipation for thermal management in dense layouts.

Part Context

This component belongs to the LTC2389 family of SAR ADCs. The IUK-18 variant specifically denotes the industrial temperature grade housed in a 48-lead QFN package. The TRPBF suffix specifies the tape and reel shipping format.
