Overview
The MAX11202BEUB+T is a 24-bit, single-channel, ultra-low-power delta-sigma analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is renowned for its high resolution and low power consumption, making it ideal for applications requiring high dynamic range and minimal power usage. The MAX11202 features a high-accuracy internal oscillator that does not require any external components and provides more than 80dB rejection of 50Hz or 60Hz line noise through its internal digital filter. It operates within a temperature range of -40°C to +85°C and is packaged in a space-saving 10-pin µMAX® package.
