Overview
The MAX1301BEUP+T, produced by Analog Devices Inc./Maxim Integrated, is a multirange, low-power, 16-bit successive-approximation analog-to-digital converter (ADC). This device operates from a single +5V supply and achieves throughput rates up to 115ksps. It features a switched-capacitor track-and-hold (T/H) architecture, allowing the analog input signal to be stored as charge on sampling capacitors. The MAX1301 is designed for applications requiring high precision and flexibility in input range programming.
