description
The TLC107x operational amplifiers offer ultra-
low offset voltage, high gain, 110-kHz bandwidth,
47-V/ms slew rate, and just 150-µW power
dissipation per amplifier.

With a supply voltage of 1.4 V, common-mode
input to the negative rail, and output swing to the
negative rail, the TLC107xC is an ideal solution for
low-voltage battery-operated systems. The
20-mA output drive capability means that the
TLC107xcaneasilydrivesmallresistiveandlarge
capacitive loads when needed, while maintaining
ultra-low standby power dissipation.
