Taiwan Semiconductor

Document Number: DS_P0000198 1 Version: B15

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

TS393 Taiwan Semiconductor ELECTRICAL CHARACTERISTICS Note: 1. The max. Output current may be as high as 20mA, independent of the magnitude of VCC, output short circuits to VCC can cause excessive heating and eventual destruction. 2. This magnitude of input current will only occur if the input leads are driven more negative than ground or the negative supply voltage. This is due to the input PNP collector base junction becoming forward biased acting as an input clamp diode.

TS393 Taiwan Semiconductor 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.
