Provides high impedance at high frequencies so that R may decouple a highly capacitive load and reduce. F supply decoupling capacitors as. It is recommended that 0. Distributors for availability and specifications. When operating two or more amplifiers in parallel mode the. If the value of R IN is decreased then the value of. Bridged Amplifier Application Circuit. Additionally, it is best to use washers under the.

I chose to use the LM in parallel configuration. Limits the voltage difference between the amplifier’s inputs for single supply operation. Datasheer -3dB point can be found from.

Human body model, pF discharged through a 1. C, the LM shuts. This can be accomplished as shown in the Typical Applica. Typical Audio Amplifier Application Circuit. LM will enter play mode when the voltage at xatasheet A is. Frequency Response of Demo Board. The power supply schematic can be found here.


In comparing audio amplifiers it is necessary to measure the. However, electrolytic capacitors are less linear. Works with R SN to stabilize the output stage by creating a pole that reduces high frequency instabilities.

Optional components dependent upon specific design requirements. Ideally a ground is a ground, but. To achieve a transient free power-up and power-down, the. R IN can be found from Equation 8 shown below: The clamp does not, however, use internal clamping. The optional external components shown in Figure 4 and.

C, then the thermal resistance for the.

Each amplifier of the LM has an independent smooth. When open or switched to GND, the amplifier will be in mute mode.

The larger the supply by. PCB layout will affect cross talk. The chassis ddatasheet were re-used from an old amp and there was a lot of filing and drilling involved to make sure none of the old silkscreen was visible.

A simple circuit like the one shown below may be. The gain of each amplifier is set lm4870 resistors R f and R i for the. These oscillations usually involve. Thus, the signal will swing around half-supply much like it. Over tightening the mounting screws will cause the package. Auxiliary Amplifier Application Circuit. By using larger values of capacitors such that the.


I had read several gleaming reviews about gainclones and the great sound that is fairly easily achievable, but I usually take internet reviews with a grain of salt.

The heart of the amplifier system is the power supply transformer s. This resistor stabilizes the.

LM4780 Gainclone

The addition of the finite wire. Acts as a volume control by setting the input voltage level. Ideally, each amplifier shares. The LM has two operational amplifiers internally, allow.

Common Mode Input Voltage. LM is datasheft directly to a capacitor with no series. Typical signal-to-noise figures are listed for an A-weighted. A bridge amplifier design has a distinct advantage over the. With large values of R IN oscillations may be observed on the. It is recommended that input and. Coming soon Conclusions and Listening Impressions I was absolutely floored by the sound quality of this amplifier.

Also suppresses external electromagnetic switching noise created from fluorescent lamps.

It just plain makes sense to use a decent one.
