The AGC gain is given by: Gvagc = 20log (Vo13 / Vo10) [dB]. ∗2 Measure the output voltages Vo0 and Vo.5 on pin 5 when currents of Is5 = 0, and Is5 = 0.5mA are applied. The input resistance is given by: ZIN5 = {0.0005 / (Vo.5 Vo0) 1 / 400} –1 [ Ω] ∗3 Input a sine wave of f = 300Hz to pin 5. Adjust the input level until the output amplitude on pin 10 is 0.15VP-P and 1.0VP-P, and measure the correspond- ing output amplitudes on pin 13 (Vo0.15 and Vo1.0). The AGC control sensitivity is given by: ∆AGC / V = 20log (Vo1.0 / Vo0.15) [dB]. ∗4 Input a sine wave of f = 300Hz to pin 5. Adjust the input level until the output amplitude on pin 10 is 300mVP-P. Measure the output amplitude on pin 13. ∗5 With pin 13 floating, measure the output voltage Vocent. Increase Vs13 from 0V, and record VINH as the Vs13 voltage when the pin 1 output exceeds 2.8V. Decrease Vs13 from 1.5V, and record VINL as the Vs13 voltage when the pin 1 output goes below 0.2V.
