1°C Temperature Sensor with Beta Compensation  
Datasheet  
„
‘1’ - The ALERT pin acts in comparator mode as described in Section 5.3.2. In this mode the  
MASK_ALL bit is ignored.  
Bit 4 - RECD1 - Disables the Resistance Error Correction (REC) for External Diode 1.  
„
„
‘0’ (default)- REC is enabled for External Diode 1.  
‘1’ - REC is disabled for External Diode 1.  
Bit 3 - RECD2 - Disables the Resistance Error Correction (REC) for External Diode 2 and External  
Diode 3.  
„
„
‘0’ (default) - REC is enabled for External Diode 2 and External Diode 3.  
‘1’ - REC is disabled for External Diode 2 and External Diode 3.  
Bit 2 - RANGE - Configures the measurement range and data format of the temperature channels.  
„
‘0’ (default) - The temperature measurement range is 0°C to +127.875°C and the data format is  
binary.  
„
‘1’ -The temperature measurement range is -64°C to +191.875°C and the data format is offset  
binary (see Table 5.3).  
Bit 1 - DAVG_DIS - Disables the dynamic averaging feature on all temperature channels.  
„
‘0’ (default) - The dynamic averaging feature is enabled. All temperature channels will be converted  
with an averaging factor that is based on the conversion rate as shown in Table 5.1 and Table 5.2.  
„
‘1’ - The dynamic averaging feature is disabled. All temperature channels will be converted with a  
maximum averaging factor of 1x (equivalent to 11-bit conversion). For higher conversion rates, this  
averaging factor will be reduced as shown in Table 5.1 and Table 5.2.  
Bit 0 - APDD (EMC1404 only) - Disables the anti-parallel diode operation. Beta Compensation is  
disabled on External Diode 2 and 3 regardless of APDD setting. In addition, External Diode 2 Beta  
Configuration register will be ignored.  
„
‘0’ (default) - Anti-parallel diode mode is enabled. Two external diodes will be measured on the  
DP2 and DN2 pins.  
„
‘1’ - Anti-parallel diode mode is disabled. Only one external diode will be measured on the DP2  
and DN2 pins.

CONV[3:0]  
The Conversion Rate Register controls how often the temperature measurement channels are updated  
and compared against the limits. This register is fully accessible at either address.  
Bits 3-0 - CONV[3:0] - Determines the conversion rate as shown in Table 6.6.
