LT1803/LT1804/LT1805
180345f
If both amplifiers are loaded simultaneously, then the total
power dissipation is 0.19W.
The maximum ambient temperature that the part is al-
lowed to operate is:
TA = TJ – (PDMAX 190°C/W)
= 150
°C – (0.190W 190°C/W) = 113.9°C
Similar calculations can be carried out for specific pack-
ages and conditions.
Also worth noting, the DD package includes a low
θJA
underside metal which is internally connected to VS–. If the
underside metal is properly soldered to a PCB, the
θJA of
the part will be close to 50
°C/W. This θJA is significantly
less than leaving the underside metal unattached and can
be useful for certain applications.
Input Offset Voltage
The input offset voltage will change greatly based upon
which input stage is active. The PNP input stage is active
from the negative supply voltage to about 1.3V below the
positive supply rail, then the NPN input stage is activated
for the remaining input range up to the positive supply rail
during which the PNP stage remains inactive. The offset
voltage is typically less than 1000
V in the range the PNP
input stage is active.
Input Bias Current
The LT1803/LT1804/LT1805 employ a patent-pending
technique to reduce the input bias current to less than 1
A
for the input common mode voltage range of 0.2V above
the negative supply rail to 1.75V below the positive rail.
The low input offset voltage and low input bias current
provide precision performance in high source impedance
applications.
Output
The LT1803/LT1804/LT1805 can deliver a large output
current, so the short-circuit current limit is set around
50mA to prevent damage to the device. Attention must be
paid to keep the junction temperature of the IC below the
absolute maximum rating of 150
°C (refer to the Power
Dissipation section) when the output is continuously short
circuited. The output of the amplifier has reverse-biased
diodes connected to each supply. If the output is forced
beyond either supply, unlimited current will flow through
these diodes. If the current is transient and limited to less
than 100mA and the total supply voltage is less than
