 The LM90 is a digital temperature sensor. It senses its own temperature as
 well as the temperature of up to one external diode. It is compatible

 Note that there is no easy way to differentiate between the MAX6657,
 MAX6658 and MAX6659 variants. The extra address and features of the

 The specificity of this family of chipsets over the ADM1021/LM84
