... Note: A pulsing output under continuous thermal overload results as the device heats and cools. Fixed Differential Gain (AS1703 The AS1703, AS1704, and AS1705 contain different internally-fixed gains fixed gain facilitates simplified designs, decreased footprint size, and elimination of external gain-setting resistors. The fixed gain values are achieved using resistors R ...

... Well designed PC board layout is essential for optimizing device performance. Use large traces for the power supply inputs and amplifier outputs to minimize losses due to parasitic trace resistance and route heat away from the device. Good grounding improves audio performance and prevents digital switching noise from coupling onto the audio signal. www.austriamicrosystems.com Table 4 and Table 5 ...
