MAX1305ECM+

Analog To Digital Converters (ADC) Overview

The MAX1305ECM+ is a 12-bit, four-channel simultaneous-sampling analog-to-digital converter (ADC) from Analog Devices/Maxim Integrated. It features independent track-and-hold circuitry for each channel and supports a 0 to +5V input range with ±6V fault tolerance. The device operates on a +4.75V to +5.25V analog supply and a +2.7V to +5.25V digital supply, consuming 57mA total current. It provides an 8-bit bidirectional parallel data bus and includes internal or external reference options. The component is housed in a 48-pin LQFP package and functions within the -40°C to +85°C temperature range.
