Description
The TS3022 dual comparator features a high-
speed response time with rail-to-rail inputs. With a
supply voltage specified from 2 to 5 V, this
comparator can operate over a wide temperature
range: -40° C to +125° C.
The TS3022 comparator offers micropower
consumption as low as a few tens of
microamperes thus providing an excellent ratio of
power consumption current versus response time.
The TS3022 includes push-pull outputs and is
available in small packages (SMD): SO-8 and
MiniSO-8.

4. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.

5. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins are floating.

6. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.

1. All values over the temperature range are guaranteed through correlation and simulation. No production test is performed
at the temperature range limits.
2. Maximum values include unavoidable inaccuracies of the industrial tests.
3. Response time is measured at 50% of final output value with following conditions: inverting input voltage (IN-) = V
ICM
and
non-inverting input voltage (IN+) moving from V
ICM
- 100 mV to V
