Overview
The MAX1230BETI+T is a 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of a family of serial 12-bit ADCs that feature an internal reference, an internal temperature sensor, and a 16-entry first-in/first-out (FIFO) buffer. The MAX1230BETI+T is designed to minimize microprocessor I/O requirements and operates from a +5V supply. It supports a maximum sampling rate of 300ksps using an external clock and is available in 28-pin 5mm x 5mm QFN with exposed pad and 24-pin QSOP packages.
