Overview
The MAX189ACWE+T is a 12-bit Analog-to-Digital Converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is a Single-Ended Successive Approximation Register (SAR) ADC, designed for high-performance analog-to-digital conversion. It features a single input and a sampling rate of 75k samples per second, making it suitable for a wide range of applications including data acquisition, instrumentation, and industrial control. The MAX189ACWE+T operates from a single +5V supply and accepts a 0 to 5V analog input, with an external reference input allowing users to tailor the device's performance to their specific requirements. Its compact 16-SOIC package and low power consumption make it an attractive option for space-constrained designs.
