DESCRIPTION
The TS925isa RAILTO RAIL quad BiCMOS
operational amplifier optimized and fully specified
for3V and5V operation.
High output current allowslow load impedancesto driven.An internallow impedance PHANTOM
GROUND eliminatesthe needforan externalref-
erence voltageor biasing arrangement.
The TS925 exhibitsa verylow noise,lowdistortion
and high output current making this devicean
excellent choicefor high quality, low voltageor
battery operated audio/telecomsystems.
The deviceis stablefor capacitive loadsupto
500pF.
Whenthe STANDBY modeis enabled,the total
consumption dropsto 6μA(VCC= 3V).
APPLICATIONS. Headphoneamplifier. Soundcard amplifier, piezoelectric speaker. MPEG boards, multimedia systems,.... Cordless telephones and portable communica-
tion equipment. Line driver, buffer. Instrumentation withlow noiseaskey factor

Notes:1.All voltage values,except differentialvoltagearewith respectto network ground terminal. Differential voltagesare thenon-inverting inputterminalwith respecttothe invertinginput terminal.The magnitude ofinputand output voltagesmust never exceedVCC+ +0.3V. Short-circuitscan cause excessive heating. Destructive dissipationcan resultfrom simultaneous short-circuitonall amplifiers. notshort circuit outputstoVCC+ when exceeding8V:thiscan induce reliabilitydefects.
