Overview
The MAX1192ETI+T, produced by Analog Devices Inc./Maxim Integrated, is an ultra-low-power, dual, 8-bit analog-to-digital converter (ADC) designed for high-speed and low-power applications. This device features two fully differential wideband track-and-hold (T/H) inputs with a 440MHz bandwidth, capable of accepting both fully differential and single-ended signals. The MAX1192 delivers excellent dynamic performance, including a typical signal-to-noise and distortion (SINAD) of 48.6dB at an input frequency of 5.5MHz and a sampling rate of 22Msps, while consuming only 27.3mW of power. It operates from a 2.7V to 3.6V analog power supply and a separate 1.8V to 3.6V supply for the digital output driver. The device is ideal for applications in imaging, instrumentation, and digital communications due to its ultra-low power consumption and high dynamic performance.
