Overview
The MAX1208ETL+ is a 3.3V, 12-bit, 80Msps analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This ADC features a fully differential wideband track-and-hold (T/H) input amplifier, driving a low-noise internal quantizer. It is optimized for low power, small size, and high dynamic performance, particularly in baseband applications. The MAX1208 operates from a single 3.0V to 3.6V supply and consumes only 373mW while delivering a typical signal-to-noise ratio (SNR) of 68.2dB at an input frequency of 32.5MHz. It also includes a 3µW power-down mode to conserve power during idle periods.
