MEASUREMENT METHOD
1. Supply Current (ICC)
The Pin 7 current is measured with no input signal and the Standby Pin (Pin 3) open.
2. Standby Supply Current (ISTBY)
The Pin 7 current is measured when the Standby Pin (Pin 3 ) is connected to ground.
3. Standby Terminal Current (IOS)
The Pin 3 current is measured when Pin 3 is connected to ground.
4. Threshold Voltage (High to Low) (V )
THL
The Pin 3 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 3 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 2 is measured with no input signal.
7. Bias Voltage (VBIAS)
The DC voltage at Pin 4 is measured with no input signal.
8. Voltage Gain (GVA)
The voltage gain equation is as follows:
GVA = 20 log V2/V1
10
Where V1 is the input voltage at TP1 (TP4) and V2 is the measured voltage at TP2 (TP5).
9. Differential Gain (DG)
The differential gain is measured at TP3 when a staircase waveform of 10 steps is applied to TP1.
