Multiple Channel 1°C Temperature Sensors with Beta Compensation
Datasheet
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 6.2).
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 6.1.
‘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 6.1.
Bit 0 - APDD (EMC1414 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 7.6.
