GXCAS GX175U

The GX175 is a high-accuracy, low-power, NTC / PTC thermistor replacement digital temperature sensor for temperature measurement in communications, computer, consumer, environmental, industrial, and instrumentation applications. The GX175 provides ≤±0.5℃ temperature accuracy over the normal operating range of -40℃ to +125℃ with good temperature linearity. The rated operating voltage range of the GX175 is 1.6V~5.5V, and the quiescent current in actual temperature conversion is less than 45μA. The on-chip analog-to-digital converter (ADC) provides a temperature resolution of 0.0625℃. The GX175 is available in an LM75-compatible 8-Pin MSOP / SOP package that supports SMBus and I²C interfaces. Up to 27 GX175 device addresses can be mounted on one bus. The GX175 provides SMBus Alert function.
