Overview
The MAX1207ETL+ is a 3.3V, 12-bit analog-to-digital converter (ADC) designed by Analog Devices Inc./Maxim Integrated. This ADC is optimized for low power consumption, small size, and high dynamic performance. It operates from a single 3.0V to 3.6V supply and features a fully differential wideband track-and-hold (T/H) input stage, driving the internal quantizer. The MAX1207ETL+ is ideal for applications requiring high-speed and low-power conversion, making it suitable for a variety of high-performance systems.
