MAX1318ECM+T

Analog To Digital Converters (ADC) Overview

The MAX1318ECM+T is a 14-bit, 2-channel analog-to-digital converter (ADC) from the Maxim Integrated MAX1316–MAX1318 family. It features independent track/hold circuitry for simultaneous sampling of two input channels with a 0 to +5V unipolar range and ±6.0V fault-tolerant inputs. The device operates from a +4.75V to +5.25V analog supply and a separate +2.7V to +5.25V digital supply, consuming less than 50mA total current. It provides an external-clock throughput of 455ksps per channel and includes internal or external reference options. The component is housed in a 48-pin LQFP package and supports operation over an extended temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Independent track/hold circuitry enables simultaneous sampling across all active channels to preserve relative phase information.
• Flexible analog input ranges include 0 to +5V, ±5V, and ±10V configurations with integrated fault tolerance.
• Configurable power management allows unused channels to be masked via a write-only configuration register.
• Integrated shutdown mode significantly reduces power consumption when the device is not actively converting.
