DESCRIPTION
Operating from a single +5 V supply, the TK15406 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 Ω load. The standard video input signal
(1 V
6 dB to produce 2 V
and 75 Ω cable load. During standby (Pin 1 grounded), the
TK15406 consumes only 120 µW of power. Nominal
power dissipation (no input) is typically 32 mW.

MEASUREMENT METHOD
1. Supply Current (ICC)
The Pin 6 current is measured with no input signal and the Standby Pin (Pin 1) open.
2. Standby Supply Current (I
The Pin 6 current is measured when the Standby Pin (Pin 1) is connected to ground.
STBY
)
3. Standby Terminal Current (IOS)
The Pin 1 current is measured when Pin 1 is connected to ground.
4. Threshold Voltage (High to Low) (V
The Pin 1 voltage is measured at the point which changes the device from operating mode into standby mode.
THL
)
5. Threshold Voltage (Low to High) (V
The Pin 1 voltage is measured at the point which changes the device from standby mode into operating mode.
6. Bias Voltage (V
The DC voltage at Pin 4 is measured with no input signal.
BIAS
)
TLH
)
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. 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.
9. Total Harmonic Distortion (THD)
The TP3 signal is measured when a 1 kHz 1 V

A 1 kHz input signal is applied to TP1 and the amplitude is slowly increased. The output voltage at TP2 is measured at
