Overview
The MAX1193ETI+T is an ultra-low-power, dual 8-bit, 45Msps analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. 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 MAX1193ETI+T is notable for its excellent dynamic performance, ultra-low power consumption of 57mW during normal operation, and three power-down modes to conserve power during idle periods. It operates from a 2.7V to 3.6V analog power supply and has 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 small size and high performance.
