They have several distinct advantages over standard operational amplifier types in single supply applications. The quad amplifier can operate at supply voltages as low as 3. The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. The output voltage range also includes the negative power supply voltage. Short Circuited Protected Outputs?

They have several distinct advantages over standard operational amplifier types in single supply applications. The quad amplifier can operate at supply voltages as low as 3.

The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications.

The output voltage range also includes the negative power supply voltage. Short Circuited Protected Outputs? True Differential Input Stage? Single Supply Operation: 3. Four Amplifiers Per Package? Internally Compensated? Industry Standard Pinouts?

Split Power Supplies. The input common mode voltage or either input signal voltage should not be allowed to go negative by more than 0. The upper end of the common mode voltage range is VCC —1. Guaranteed by design. The first stage of each consists of differential input devices Q20 and Q18 with input buffer transistors Q21 and Q17 and the differential to single ended converter Q3 and Q4.

The first stage performs not only the first stage gain function but also performs the level shifting and transconductance reduction functions. By reducing the transconductance, a smaller compensation capacitor only 5.

The transconductance reduction is accomplished by splitting the collectors of Q20 and Q Another feature of this input stage is that the input common mode range can include the negative supply or ground, in single supply operation, without saturating either the input devices or the differential to single—ended converter.

The second stage consists of a standard current source load amplifier stage. Large Signal Voltage Follower Response Each amplifier is biased from an internal—voltage regulator which has a low temperature coefficient thus giving each amplifier good temperature characteristics as well as excellent power supply rejection.

Fesar Yes, it seems to be a redundant voltage limiter that will kick in at about 7. But this IC is specially designed for series regulator application. The base of the transistor is connected directly to the regulated output of the transformer, so when the transformer produces 9 volts the base voltage will be greater than or equal to the emitter voltage and the transistor will open the circuit. LM is an adjustable voltage regulator IC used for shunt regulator, dataasheet regulator, and temperature controller. See the additional analysis above.
