Product Introduction

PJ85753 is a digital temperature sensor with ±1°C accuracy. Temperature data can be read out directly via digital interface (Compatible with SMBus, I2C) by MCU, Bluetooth chip or SoC chip. PJ85753 supports I2C communication with speed up to 3.4 MHz. Each chip is specially calibrated for ±1°C (Max.) accuracy over-20°C to 100°C range in factory before shipment to customers. There is no need for re-calibration anymore for ±1°C accuracy. 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. Available Package : SOT23-5.
