Taiwan Semiconductor
Low Power Low Offset Voltage Dual Comparators
GENERAL DESCRIPTION
The TS393 is dual independent precision voltage
comparators capable of single-supply or split-supply
operation. The specifications as low as 2.0 mV make
this device an excellent ground level with single-supply
operation. Input offset-voltage selection for many
applications in consumer automotive, and It is designed
to permit a common mode range-to- industrial
electronics.
FEATURES
● Output voltage compatible with DTL, ECL, TTL,
MOS and CMOS Logic levels
● Low input bias current 25nA
● Low input offset current ±0.5nA
● Low input offset voltage ±2mV (typ)
● Input common mode range to ground level
● Differential input voltage range equal to power
supply voltage
● Very low supply current drain (0.4mA) –
independent of supply voltage
● Wide single-supply range 2V~36V
● Split- supply range ±1V to ±18V

APPLICATION INFORMATION
This dual comparator feature high gain, wide bandwidth characteristics. This gives the device oscillation tendencies
if the outputs are capacitive coupled to the inputs via stray capacitance. This oscillation manifests itself during
output transitions (VOL to VOH). To alleviate this situation input resistors<10kΩ should be used. The addition of
positive feedback (<10 mV) is also recommended. It is good design practice to ground all unused pins. Differential
input voltages may be larger than supply voltage without damaging the comparator's inputs. Voltages more
negative than -0.3V should not be used.
