APPLICATIONS INFORMATION Fig1: Using a Series Resistor in a Unity-Gain Configuration VDD R Input The TK62022F TK62022F has higher gain-bandwidth product than competitors with similar supply current. The IC consumes only 250µA per amplifier while offering 5MHz of gain-bandwidth product. The IC has rail-to-rail input and output capability, allowing wide dynamic range especially in low voltage applications. The IC is stable in a unity-gain configuration. The IC is offered in a space saving SON-8 package. The IC is designed for portable applications with low power and space requirements.

Rail-to-Rail Input Input signal 0 200m -50m 150m -100m 100m -150m 50m -200m Output signal -250m Rail-to-rail input is achieved with a complementary input stage. The input stage consists of an n-channel differential pair in parallel with a p-channel differential pair. If the input voltage exceeds 0.3V above the supply voltage, the internal ESD protection diode can cause excessive current to the input pin. Be careful to insure the input voltage does not exceed the supply voltage. -300m 0 10u -100m 20u Fig3: Step Response with a Series Resistor RL=100k, CL=1000pF, R=100 100m Input Voltage [V] 50m Input signal 0 200m -50m 150m -100m 100m -150m 50m -200m -300m The TK62022F TK62022F is stable in a unity-gain configuration. When driving a large capacitive load in a unity-gain configuration, it is recommended to insert a small resistor in series with the output. The series resistor will reduce ringing.
