TK17010 LOW VOLTAGE OPERATIONAL AMPLIFIER FEATURES s Very Low and Wide Operating Voltage Range (VOP = 1.0 to 7 V) s Very Wide Input Signal Voltage Range (VIN = 0 V to 1.4 VP-P) s Very Large Output Signal (VOUT(MAX) = 1.4 VP-P) s Very Large Output (Source) Current (IOUT(MAX) = 660 µA) s Very Small SOT23L-6 Package APPLICATIONS s Battery-Powered Equipment DESCRIPTION The TK17010 is a single-supply operational amplifier capable of operating from a very low and very wide supply voltage range (VCC = 1.0 to 7 V). With its rail-to-rail structures, the input signal circuit can accept a very wide input voltage range (VIN = 0 to 1.4 VP-P). The TK17010 can also provide a very large output signal (VOUT(MAX) = 1.4 VP-P) while operating from a single 1.5 volt supply. This makes the TK17010 ideal for battery-operated equipment. The TK17010 is available in the very small SOT23L-6 Surface Mount Package.
