Overview
The MAX1031BETI+ is a 10-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX1027/MAX1029/MAX1031 family, which features high-performance, multichannel ADCs with integrated temperature-sensing capabilities. The MAX1031BETI+ is particularly notable for its 16 input channels, which can be configured as either single-ended or differential inputs in unipolar or bipolar mode. It operates from a single +3V supply and includes an internal reference, internal temperature sensor, and on-chip FIFO. The device supports a maximum sampling rate of 300ksps using an external clock and features a 10MHz SPI/QSPI/MICROWIRE-compatible serial interface for easy microprocessor control.
