Overview
The MAX1301BEUP+TCAL is a multirange, low-power, 16-bit, successive-approximation analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device operates from a single +5V supply and achieves throughput rates up to 115ksps. It features a separate digital supply, allowing digital interfacing with systems using voltages between 2.7V and 5.25V through an SPI-/QSPI-/MICROWIRE®-compatible serial interface. The MAX1301 is designed for applications requiring high precision and flexibility in analog input configurations.
