DS2450S+T&R

Analog To Digital Converters (ADC) Overview

The DS2450S+T&R is a quad analog-to-digital converter utilizing the 1-Wire interface. It features four high-impedance inputs for measuring analog voltages, supporting user-programmable input ranges of 2.56V or 5.12V and resolutions from 1 to 16 bits. The device operates on a single 5V supply with active power consumption of 2.5 mW and idle consumption of 25 μW. Communication occurs at up to 16.3 kbps, boostable to 142 kbps via overdrive mode. It includes a factory-lasered 64-bit registration number for unique identification and alarm thresholds for conditional search capabilities.
