Overview
The MAX19192ETI+T is a dual-channel, ultra-low-power, 8-bit analog-to-digital converter (ADC) designed by Analog Devices Inc./Maxim Integrated. This device is part of the MAX19191 family but offers a dual-channel configuration, making it ideal for applications requiring simultaneous sampling of two analog signals. The MAX19192ETI+T features a fully differential wideband track-and-hold (T/H) input, supporting both fully differential and single-ended analog inputs.
