LA4192
No.919–5/11
Continued from preceding page.
If designated for Rf=27
, VG=56dB will be obtained which is excessive ; it is recommended that R
NF=51 be
designated when bridge amplifier is connected.
2. Crosstalk
As LA4192 is used at a voltage gain around 50dB, feedback is shallow. It is recommended that the bridge amplifier
output pin (pin 1) be grounded when used for 2-channel.
3. Starting time
A built-in muting circuit suppresses shock noise when power is turned on. It utilizes time constant of C9 (de-
coupling capacitor), and built-in charging circuits for C1 and C2 (NF capacitors). The starting time depends on
capacitances of C1 (C2) and C9 as shown below :
VG=20 log

Rf
4. Cautions for use of the IC
1. When used close to the maximum ratings, even a slight variation in conditions can cause the maximum ratings to
be surpassed. This leads to breakdown failures. Be sure to provide for sufficient margins to cover variations in
power voltages. Use the IC in a range that never exceeds the maximum ratings.
2. Inter-pin shortcircuits
Turning the power on with inter-pin shortcircuits causes breakage or deterioration, so that when mounting the IC
on a circuit board, carefully inspect to avoid inter-pin shorts caused by soldering, before turning the power on.
3. Short-circuited loads
When used for a prolonged period with a shorted load, breakage or deterioration can result. Under no circum-
stance should loads be left shorted.
4. When used in a radio or radio-cassette recorder, maintain a sufficient distance between the IC and a bar antenna.
5. In making a circuit board, refer to the sample printed pattern.
