Overview
The LTC2389CUK-16 is a 16-bit, 2.5Msps Successive Approximation Register (SAR) Analog-to-Digital Converter manufactured by Analog Devices Inc. It operates from a single 5V supply and features pin-configurable analog input ranges, supporting fully differential (±4.096V), pseudo-differential unipolar (0V to 4.096V), and pseudo-differential bipolar (±2.048V) configurations. The device integrates an internal reference and offers low power consumption of 162.5mW at full speed. It is housed in a 48-lead LQFP package and provides high linearity with DNL of 0.1 LSB and INL of 0.3 LSB.

Procurement Notes
Verify the specific suffix 'UK' against the manufacturer's official datasheet for the LTC2389 series to confirm temperature range and package details. Ensure compatibility with the required input configuration before procurement. Check for RoHS compliance status as indicated in official documentation.
Selection Notes
Select this component when a 16-bit resolution and 2.5Msps throughput are required with flexible input range options. The internal reference simplifies design by reducing external component count. Consider the LQFP-48 package size for PCB layout constraints.
Part Context
The LTC2389 series includes 16-bit and 18-bit variants. The LTC2389CUK-16 specifically denotes the 16-bit version. Evaluation boards such as DC1826A-A are available for testing similar devices in the series, facilitating development and validation of signal chain performance.
Replacement Considerations
Direct substitutes within the same family include other LTC2389 variants with different resolutions or input ranges. Verify pin compatibility and electrical specifications before substitution.
