Overview
The MAX1308ECM+T is an 8-channel, 12-bit, simultaneous sampling analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is housed in a 48-pin LQFP package and features independent track-and-hold (T/H) circuitry, allowing for simultaneous sampling of all active channels. This preserves relative phase information, which is crucial for applications requiring precise timing and synchronization.
The MAX1308ECM+T offers a ±5V analogue input range with ±16.5V fault-tolerant inputs, making it robust against input voltage variations. It also includes internal or external reference and clock capabilities, enhancing flexibility and ease of use.
