Overview
The MAX1202BCAP+ is a 12-bit, 8-channel serial analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This component is designed for applications requiring mixed +5V (analog) and +3V (digital) supply voltages. It combines an 8-channel multiplexer, high-bandwidth track/hold, and a serial interface, making it suitable for a variety of data-acquisition systems. The MAX1202BCAP+ operates with a single +5V analog supply or dual ±5V analog supplies and features an internal 4.096V reference voltage, simplifying the design process for many applications.
