TK15405

OPERATIONAL AMPLIFIER WITH 75 Ω DRIVER

FEATURES

■ Fixed Gain (6 dB typ.)

■ Internal 75 Ω Driver

■ Active High ON/OFF Control with Internal Pull-up

■ Very Low Standby Current (typ. I

STBY

≤ 25 µA)

■ Very Small Output Capacitor Using SAG Function Pin

■ Very Small SOT23-6 Package

■ Single +5 V Power Supply Operation

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 Ω load. The standard video input signal
(1 V

typical) is internally clamped at 1.25 V and amplified

P-P

6 dB to produce 2 V
and 75 Ω 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 µW of power. Nominal power
dissipation (no input) is typically 38 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.

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. Clamp Voltage (V
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.
