Measurement conditions (unless otherwise noted, Ta = 25°C and V
CC
= 3V)
Measurement method
1 Input a sine wave of f = 300Hz to pin 5, and measure the output amplitudes on pins 10 and 13 (Vo10 and Vo13).
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}

3 Input a sine wave of f = 300Hz to pin 5. Adjust the input level until the output amplitude on pin 10 is 0.15V
P-P
and 1.0V
P-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 300mV
P-P
.
Measure the output amplitude on pin 13.
5 With pin 13 floating, measure the output voltage Vocent.
Increase Vs13 from 0V, and record V
IN
H as the Vs13 voltage when the pin 1 output exceeds 2.8V.
Decrease Vs13 from 1.5V, and record V
IN
L as the Vs13 voltage when the pin 1 output goes below 0.2V.

to pin 5, and measure the time that it takes CTLOUT to be output after pin 2 goes from V
CC
to 0V.
