Overview
The MAX1209ETL+T is a high-performance, 12-bit analog-to-digital converter (ADC) designed by Maxim Integrated, now part of Analog Devices Inc. This component is optimized for intermediate-frequency (IF) sampling applications and is known for its low power consumption, small size, and high dynamic performance.
It features a fully differential wideband track-and-hold (T/H) input amplifier and a low-noise internal quantizer. The ADC can accept single-ended or differential analog input signals and operates from a single 3.0V to 3.6V supply voltage.
