Signal plus weighted-noise to
5 to 8 V power supply and an alternative 12 V power supply
Low power consumption (200 mW) at 5 V supply voltage
New AC-coupled wideband IF-amplifier (high dynamic ranges, less intermodulation)
In-phase wideband AM demodulator without external reference circuit
Reduced THD figures even for low AF frequencies (typical 1%)
Stabilizer circuit for ripple rejection and constant output signals
All pins are ESD protected
