Overview
The MAX11198ATE+T is a high-performance, dual-channel Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This component is part of the MAX11192/MAX11195/MAX11198 family, offering 12-, 14-, or 16-bit resolution and simultaneous sampling at a rate of 2 million samples per second (Msps). The ADC features differential inputs and an integrated reference, which reduces board area and component count. It is packaged in a compact 16-pin, 2mm x 3mm TQFN-EP package, making it ideal for space-constrained applications.
