MAX6627MKA+T

MAX6627MKA+T is a remote ±1°C accurate digital temperature sensor with SPI-compatible serial interface. This precise digital temperature sensor reports the temperature of a remote sensor. The remote sensor is a diode-connected transistor, typically a low-cost, easily mounted 2N3904 NPN type that replaces conventional thermistors or thermocouples. The devices can also measure the die temperature of other ICs, such as microprocessors (µPs) or microcontrollers (µCs) that contain an on-chip, diode-connected transistor. Remote accuracy is ±1°C when the temperature of the remote diode is between 0°C and +125°C and the temperature of the devices is +30°C. The temperature is converted to a 12-bit + sign word with 0.0625°C resolution. The architecture of the device is capable of interpreting data as high as +145°C from the remote sensor. The MAX6627 temperature should never exceed +125°C. Applications include hard disk drive, smart battery packs, industrial control systems, notebooks, PCs.
