Overview
The MAX1202BEAP+ is a 12-bit, 8-channel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is designed for use in applications that require mixed +5V (analog) and +3V (digital) supply voltages. It combines an 8-channel multiplexer, high-bandwidth track/hold, and a serial interface, making it ideal for high-speed data acquisition with low power consumption.
The MAX1202BEAP+ operates with either a single +5V analog supply or dual ±5V analog supplies and supports direct connection to SPI/MICROWIRE® devices and TMS320-family digital signal processors without external logic.
