Measurement method ∗1 Measure the circuit current when no signal is present. ∗2 Apply a sine wave of f = 1kHz to the input, and adjust the input level so that the output distortion is 1%. At this time, set the output voltage to the maximum output level of VOM [VP-P]. ∗3 Measure the output VO [VP-P] with a sine wave of f = 4.43MHz, 1VP-P applied to the input. Voltage gain GV is: GV = 20 Log (VO / VIN) [dB] ∗4 Measure the outputs VO7 and VO1 [VP-P] each with sine waves of f = 7MHz, 1VP-P and f = 1MHz, 1VP-P applied to the input. Voltage frequency GF is: GF = 20 Log (VO7 / VO1) [dB] ∗5 Measure the output VO [VP-P] with a sine wave of f = 4.43MHz, 1VP-P applied to the input. The muting attenuation MT is: MT = 20 Log (VO / VIN) [dB] ∗6 Measure the input voltage VINSO [V] and the open voltage of the input VINO [V] when 50µA is introduced. The input impedance ZIN is: ZIN = |VINSO – VINO| / 50 × 1000 [kΩ] ∗7 Measure the circuit current when MUTEA (pin 1) is HIGH. |
