Overview
The MAX1228BEEP+ is a 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1226/MAX1228/MAX1230 family and is designed for high-performance data acquisition. It features an internal reference, an internal temperature sensor, and a 16-entry first-in/first-out (FIFO) buffer. The MAX1228BEEP+ operates from a single +5V supply and supports a maximum sampling rate of 300ksps using an external clock.
