ISTBY 25 A) s Very Small Output Capacitor Using SAG Function Pin s Very Small SOT23-6 Package s Single +5 V Power Supply Operation APPLICATIONS s s s s s s Video Equipment Digital Cameras CCD Cameras TV Monitors Video Tape Recorders LCD Projectors DESCRIPTION Operating from a single +5 V supply, the TK15405 is a single-channel video line driver IC that takes a standard video analog input and provides a buffered analog output for driving a 150 load. The standard video input signal (1 VP-P typical) is internally clamped at 1.25 V and amplified 6 dB to produce 2 VP-P (typical) into a series 75 resistor and 75 cable load. The internal 1.5 k SAG function resistor provides gain compensation for low frequency signals. During standby (Pin 1 grounded), the TK15405 consumes only 120 W of power. Nominal power dissipation (no input) is typically 38 mW. The TK15405M is available in the very small SOT23-6 surface mount package.

Supply Current (ICC) The Pin 6 current is measured with no input signal and the Standby Pin (Pin 1) open. 2. Standby Supply Current (ISTBY) The Pin 6 current is measured when the Standby Pin (Pin 1) is connected to ground. 3. Standby Terminal Current (IOS) The Pin 1 current is measured when Pin 1 is connected to ground. 4. Threshold Voltage (High to Low) (VTHL) The Pin 1 voltage is measured at the point which changes the device from operating mode into standby mode. 5. Threshold Voltage (Low to High) (VTLH) The Pin 1 voltage is measured at the point which changes the device from standby mode into operating mode. 6. Clamp Voltage (VCMP) The DC voltage at Pin 4 is measured with no input signal. 7. Voltage Gain (GVA) The voltage gain equation is as follows: GVA = 20 log10 V2/V1 Where V1 is the input voltage at TP1 and V2 is the measured output voltage at TP2. 8. Differential Gain (DG) The differential gain is measured at TP3 when a staircase waveform of 10 steps is applied to TP1. 9. Differential Phase (DP) The differential phase is measured at TP3 when a staircase waveform of 10 steps is applied to TP1. 10. Frequency Response (fr) The frequency response equation is as follows: fr = 20 log10 V2/V1 Where V1 is the measured TP3 voltage when the TP1 input frequency is set to 1 MHz and V2 is the measured TP3 voltage when the TP1 input frequency is set to 5 MHz.
