PRELIMINARY INFORMATION
TC02/03-04 6/18/97
* Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions above those
indicated in the operational sections of the specifications is not implied.
Exposure to Absolute Maximum Rating Conditions for extended periods
may affect device reliability.

DETAILED DESCRIPTION
A plot of output voltage versus temperature for both the
TC02 and TC03 appears in Figure 1. The TC03 can be
used with single power supply to measure temperatures
from 0
°
C to 100
°
C. A pull-down resistor (R1 in Figure 2)
must be added from V
OUT
to the negative power supply for
measuring temperatures less than 0
°
C. The value of the
resistor must be chosen to limit the maximum current
pulled from the output to the negative supply to
– 50
μ
A (i.e. R1 = V
SS
/50
μ
A).
Notes:
1. V
OUT
outputs open circuited.
2. Accuracy = Difference between calculated output voltage (10mV/
°
C x Device case temperature at specified temperature and power supply)
and measured output voltage expressed in
°
C.
3. Nonlinearity = deviation of output voltage versus temperature from the best-fit straight line over the device rated temperature range.
4. Guaranteed by design.
OUTPUT STAGE
Both the TC02 and TC03 have Class A output stages
capable of sourcing 1mA. These devices have a limited
ability to drive heavy capacitive loads. Loads of 50pF (to
ground) can be driven directly. For heavier loads, a 2k
(or
greater) resistor should be placed in series with the output
for decoupling. If the TC02/03 is used in a noisy electrical
environment, a 0.1
μ
F bypass capacitor from V
CC
to GND is
recommended.
