LA4167M
Continued from preceding page.
IC Usage Cautions and Explanation of Operation
(1) Playback preamp and power amp voltage gain distribution during playback
* The voltage gain of the preamp can be adjusted by resistor R2, connected externally. In this case, be aware that varying the voltage gain causes the voltage gain for the playback preamp and the mike amp to be each varied simultaneously.
No. 4036-11/20
LA4167M (2) Mike amp, REC amp, and power amp voltage gain distribution during recording
* Be aware that during recording, the power amp is not BTL, and there is single operation for only power amp 2. (3) VOX circuit (VOX equivalent circuit)
* VOX on time can be adjusted by varying C8 at pin 6. Increasing the capacitance delays attack time, and reducing capacitances hastens it (VOX on = Approx. 40 ms when C8 = 4.7 F and C9 = 22 F). * VOX off time can be adjusted by varying C9 at pin 7 (VOX off = Approx. 4s when C8 = 4.7 F and C9 = 22 F). * To continue VOX circuit operation when MIC input is below the specified level, increase the capacitance of the capacitor between pin 7 and VCC. * To keep the governor circuit on after the VOX circuit is switched off, turn on the switch and ground pin 7 in the equivalent circuit shown above. * Only a capacitor is mounted between pin 6 and ground. A resistor is not mounted because when the VOX circuit is turned on, a minute charging current is present at pin 6, and the resistance would bypass this minute current, causing a delay in operation and, in the worst case, failure of the VOX circuit to operate.
* The VOX circuit has a hysteresis width of approximately 6 dB. But as shown in the figure above, the VOX circuit is switched on when the voltage at pin 6 is over approximately 1.3 V, and is switched off when voltage is below approximately 0.7 V. The bias to keep the VOX circuit on at this time must be an average or smooth voltage over approximately 0.75 V.
No. 4036-12/20
LA4167M (4) Cue-tone (externally mounted cue-tone circuit)
* Cue-tone begins to operate at the pin 8 ground, as shown in the figure above. The LED goes out at this time. * Capacitors C10 and C11 for cue-tone operation must be of high quality and of identical precision. * Capacitors C10 and C11 can be varied to change the cue-tone frequency. Increasing the capacitance of C10 and C11 delays the frequency, and decreasing this capacitance hastens it. In the external circuit shown above, fOSC = Approx. 15 Hz. (5) R/P mute (mute circuit during R/P switching)
* In the mute circuit depicted above, a minute pulse is input to pin 21 as shown in the figure to switch from REC to PLAY or from PLAY to REC. At this time, current is determined by: E2-E IM= R13 1 In this case, 2.0V-1.5V IM= =16.7A 30k * Muting capacitors C19 and C20 are used to adjust the muting time: muting time increases when capacitance is high and decreases when capacitance is low. Be aware, however, that if capacitance is excessive, power amp onset is delayed when VCC is on. Capacitance of 0.1 F to 1 F is recommended. * If voltage over 1.6 V is applied to the mute pin when VCC = 3.0 V, each amp is muted. Be aware that application of voltage higher than VCC in this case will disable muting. * The power, REC, VOX, and ALC amps can be muted.
No. 4036-13/20
LA4167M (6) LEDs
* Pin 24 is dedicated to LED use. The LED is lit during normal operation, and goes out only when cue-tone is on in the recording mode. * With 10 mA typ. at 3.0 V for ILED at the LED pin, it is possible to switch between red and green LEDs as shown in the diagram below.
* The LED pin should be left open if not used.
