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 )
STBY
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.
