Among the series products of RAMSUN temperature sensor IC, the sensor temperature measurement range of IIC/SMBus digital two-wire and three-wire interface is -55°C-+135°C, and the accuracy is from ±1°C-±0.1°C. The fastest temperature conversion speed can reach 2ms, the average power consumption is less than 1uA/s, and the resolution ranges from 8bit to 16bit. It has the characteristics of high precision, strong anti-interference ability, low power consumption, and high consistency. Its application fields cover communications and white goods. , consumer electronics, industrial control, Internet of Things and smart wearable fields and other scenarios.
It is a domestic I2C/SMBus interface digital temperature sensor IC that can replace TMP103. The temperature sensor is packaged in a four-ball wafer level package, and the temperature measurement resolution is 1°C, and the temperature measurement resolution is 0.125°C. The two-wire interface is compatible with SMBus and I2C communication methods, and supports multi-chip access (MDA) commands, enabling the host to communicate with multiple chips on the bus at the same time, without sending read and write commands to each chip separately. Supports mounting up to 8 different address chips on one main line, and supports mounting 16 different address chips. It is suitable for systems with limited temperature measurement areas, sensitive to temperature, and requiring measurement and monitoring of multiple temperature areas. The rated operating temperature range is -40°C~+125°C. The accuracy is ±0.5℃; the conversion speed is less than 26ms; the electrostatic protection is 4KV; the average power consumption is 3uA.
