The PJ85451 is a 2 channels (1 remote channel + 1 local channel) digital temperature sensor. Temperature data can be read out directly via digital interface (compatible SMBus and I2C with speed up to 400 kHz) by MCU, Bluetooth Chip or SoC chip. Each chip is specially calibrated ±1.0°C (Max.) accuracy for both remote and local channel over 0°C to 85°C temperature range in factory before shipment to customers. It includes a high precision band-gap circuit, a 12-bit analog to digital converter that can offer 0.0625°C resolution, a calibration unit with non volatile memory, and a digital interface block. It has a feature of series resistance cancellation for remote channel. It also has non-ideality factor correction feature for remote channel by programming register. Available Package : DFN2x2-8 package.
