MAX6627 Datasheet ACcurate Digital Temperature Sensors

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX6627/MAX6628 Remote ±1°C Accurate Digital Temperature Sensors with SPI-patible Serial Interface.

General Description

The MAX6627/MAX6628 precise digital temperature sensors report 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.
