Sensor with Beta  
Compensation  
(for <45ꢀnm Geometries)  
http://onsemi.com  
The ADT7421 is a dual-channel digital thermometer and  
under/overtemperature alarm, intended for use in PCs and thermal  
management systems. It is pin- and register-compatible with the  
ADM1032, ADT7461 and ADT7461A.  
The ADT7421 includes Beta Cancellation Technology. This enables  
accurate measurement of temperature from very small geometry  
(45 nm) processes. Significant variations in the Beta factor can be  
observed when different currents are applied to transistors embedded  
in small geometry CPU’s. This leads to large temperature errors. The  
ADT7421 automatically cancels the effects of error induced by beta  
variations.
