Product Description
Product Overview
The GX1820 is a programmable resolution single-bus temperature sensor featuring a global unique 64-bit serial number, multi-point distributed temperature measurement, and no external components required. It operates with a supply voltage range of 2.5V to 5.5V, offering a measurement range of -55C to +125C with an accuracy of 0.5C within the -10C to 70C range. The temperature resolution is selectable from 9 to 12 bits, with a conversion speed of less than 750ms at 12-bit precision. It also includes user-definable non-volatile temperature alarm settings and strong electrostatic protection.
