MEASUREMENT METHOD
1. Supply Current (I
)
The Pin 1 current is measured with no input signal and the Standby Pin (Pin 2) open.
2. Standby Supply Current (I
)
The Pin 1 current is measured when the Standby Pin (Pin 2) is connected to ground.
3. Standby Terminal Current (I
)
The Pin 2 current is measured when Pin 2 is connected to ground.
4. Threshold Voltage (High to Low) (V
)
The Pin 2 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 2 voltage is measured at the point which changes the device from standby mode into operating mode.
6. Voltage Gain (GVA)
The voltage gain equation is as follows:
GVA = 20 log
V2/V1
Where V1 is the input voltage at TP1 and V2 is the measured output voltage at TP2.
V1 and V2 are measured for the other channels in the same manner.
7. Frequency Response (fr)
The frequency response equation is as follows:
fr = 20 log
V2/V1
Where V1 is the measured TP2 voltage when the TP1 input frequency is set to 1 MHz and V2 is the measured TP2 voltage
when the TP1 input frequency is set to 5 MHz. Furthermore, V1 is the measured TP2 voltage when the TP1 input frequency
is set to 1 MHz and V2 is the measured TP2 voltage when the TP1 input frequency is set to 10 MHz.
V1 and V2 are measured for the other channels in the same manner.
