4) If the IC is used near the maximum ratings, even a slight variation in conditions may cause the maximum ratings to be

exceeded, thereby leading to breakdown. Allow an ample margin of variation for supply voltage etc. and use the IC in the

range where the maximum ratings are not exceeded. exceeded.

5) Short Circuits Between Pins

The circuit board should be examined for short circuits between pins before initial power-up to prevent damage to the device

when voltage is applied.

6) Short-circuit Load

Short circuiting the LA2806M output for an extended period while the power is on can damage the device.

7) Playback Amplifier and Preamplifier Feedback Resistance

As the playback amplifier and preamplifier employ a zero-bias method, the amplifier’s output DC level (VODC) is determined

by the feedback resistance (RNF) and the NF pin sink current (Ii = 15 µA).

VODC = VBE + RNF × Ii

VBE 6 0.7 V

A feedback resistance of 100 kΩ is recommended for both the playback amplifier and the preamplifier to provide an output

DC level with sufficient output dynamic range.
