LA4629
Monolithic Linear IC
LA4629
Two-Channel Audio Frequency Power Amplifier
Overview
The LA4629 is a 2-channel power amplifier developed for use in radio/cassette player products.
The LA4629 reduces the number of required external components by 50% over earlier products
(BS/NF capacitors and oscillation prevention RC
components) and thus can contribute significantly
to space saving in end products.
Features
•
Provided in the SIP12H package.
•PO : 2.5 W ✕ 2 (VCC = 9 V, RL = 3 Ω)
4.5 W ✕ 2 (VCC = 12 V, RL = 3 Ω)
: 2.0 W ✕ 2 (VCC = 9 V, RL = 4 Ω)
4.0 W ✕ 2 (VCC = 12 V, RL = 4 Ω)
• Standby function built in
(supports direct microcontroller control).
• Built-in thermal protection circuit.

• Pins 4 and 11 must be left open.
*• Rx: If the STBY pin (pin 6) is used, observe the following:
Insert the resistor Rx in series to limit the inflowing current.
(The amplifier will be on when a voltage is applied to pin 6.)
