LTC2389CUK-18#TRPBF

Overview

The LTC2389CUK-18#TRPBF is a low noise, high speed 18-bit successive approximation register (SAR) ADC from Analog Devices Inc. Operating from a single 5V supply, it supports pin-configurable fully differential (±4.096V), pseudo-differential unipolar (0V to 4.096V), and pseudo-differential bipolar (±2.048V) analog input ranges. It achieves ±3LSB maximum INL with no missing codes at 18 bits. The device features an internal precision 4.096V reference with guaranteed 0.5% initial accuracy and ±20ppm/°C temperature coefficient. It dissipates 162.5mW at 2.5Msps throughput.

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for the UK package variant. Confirm the C grade corresponds to the 0°C to 70°C operating temperature range. Ensure compatibility with the required OVDD voltage levels for the digital interface.

Selection Notes

Select this part when 18-bit resolution and 2.5Msps speed are required in a QFN package. The C grade is suitable for commercial applications within 0°C to 70°C. For wider temperature ranges, consider the I or H grades. Verify that the internal reference meets system accuracy requirements or use an external reference if higher precision is needed.

Part Context

This component belongs to the LTC2389-18 family of 18-bit SAR ADCs. The UK suffix denotes the 48-lead 7mm × 7mm Plastic QFN package. The TRPBF suffix specifies tape and reel packaging with lead-free finish. The C grade indicates a commercial temperature range of 0°C to 70°C.
