Overview
The MAX1379ATP+T, produced by Analog Devices Inc./Maxim Integrated, is a dual, 12-bit, 1.25Msps (mega-samples per second) simultaneous-sampling analog-to-digital converter (ADC). This component is part of the MAX1377/MAX1379/MAX1383 family, known for their low power consumption, high sampling rates, and excellent dynamic performance. The MAX1379 operates from an analog supply voltage of 4.75V to 5.25V and supports a separate digital supply voltage of 1.8V to AVDD, enabling easy interfacing with low-voltage logic without the need for level translators.
