Overview
The MAX1247CCPE is a 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1247 series, which combines a 4-channel multiplexer, high-bandwidth track/hold, and a serial interface. It operates from a single supply voltage ranging from +2.7V to +5.25V, making it suitable for low-power applications. The MAX1247 is designed for high conversion speed and low power consumption, with features such as software-configurable analog inputs for unipolar/bipolar and single-ended/differential operation.
