PARAMETER DEFINITIONS  
Thermal Hysteresis  
Temperature Coefficient  
Thermal Hysteresis is defined as the change of output voltage  
after the device is cycled through temperature from +25°C to  
–40°C to +125°C and back to +25°C. This is a typical value  
from a sample of parts put through such a cycle.  
The change of output voltage over the operating temperature  
range and normalized by the output voltage at 25°C, expressed  
in ppm/°C. The equation follows:  
VO(T2 )–VO(T )  
VO(25°C)×(T2 – T )  
TCVO ppm/°C  
=
×106  
VO _HYS =VO (25°C)–VO _TC  
VO(25°C)–VO _TC

O (25°C) = VO at 25°C

O (T2) = VO at Temperature 2.

V
O_TC = VO at 25°C after temperature cycle at +25°C to –40°C  
to +125°C and back to +25°C.  
Line Regulation  
The change in output voltage due to a specified change in input  
voltage. It includes the effects of self-heating. Line regulation is  
expressed in either percent per volt, parts-per-million per volt,  
or microvolts per volt change in input voltage  
Input Capacitor  
Input capacitors are not required on the ADR42x. There is no  
limit for the value of the capacitor used on the input, but a 1 µF to  
10 µF capacitor on the input will improve transient response in  
applications where the supply suddenly changes. An additional  
0.1 µF in parallel will also help to reduce noise from the supply.  
Load Regulation  
The change in output voltage due to a specified change in load  
current. It includes the effects of self-heating. Load Regulation  
is expressed in either microvolts per milliampere, parts-per-  
million per milliampere, or ohms of dc output resistance.  
Output Capacitor  
The ADR42x does not need output capacitors for stability  
under any load condition. An output capacitor, typical 0.1 µF,  
will filter out any low-level noise voltage and will not affect  
the operation of the part. On the other hand, the load transient  
response can be improved with an additional 1 µF to 10 µF  
output capacitor in parallel. A capacitor here will act as a source  
of stored energy for sudden increase in load current. The only  
parameter that will degrade, by adding an output capacitor,  
is turn-on time and it depends on the size of the capacitor chosen.  
Long-Term Stability  
Typical shift of output voltage at 25°C on a sample of parts  
subjected to operation life test of 1000 hours at 125°C:  
∆VO = VO(t0 ) – VO(t1)  
VO(t0 ) – VO(t1)  
∆VO (ppm) =  
× 106  
VO(t0 )  
where

O (t0) = VO at 25°C at Time 0  
O (t1) = VO at 25°C after 1000 hours operation at 125°C.
