Overview
The MAX1108EUB+T, produced by Analog Devices Inc./Maxim Integrated, is a low-power, 8-bit, dual-channel analog-to-digital converter (ADC). This device is part of the MAX1108 series, which is known for its high efficiency and versatility. The MAX1108 operates on a single supply voltage ranging from +2.7V to +3.6V and consumes only 105µA at 50ksps, making it an ideal choice for power-sensitive applications. It features an internal track/hold (T/H) voltage reference, clock, and a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE devices without the need for external logic.
