Hybrid Power Oscillator

The OSC1758 is a hybrid sine/cosine power oscillator which can provide a maximum power output of 1.5 watts, over 0 to 10kHz.

The device comprises two independent parts-an oscillator and a power amplifier.

The oscillator stage has two signal outputs, one 90° in phase advance with respect to the other.

The oscillator frequency is programmable in the range of 0 to 10kHz by two identical external capacitors.

The power amplifier stage is externally short circuit protected and has a gain of 2.8 ± 1% The maximum output current this stage can produce is 215mA rms (at 7V rms)

Connecting either of the oscillator stage outputs to the power amplifier input, using an external link, will givea nominal output of 7 volts rms. Lower voltages can be obtained by connecting an external resistor in series with the amplifier's inputs.

The OSC1758 is housed in an hermetically-sealed 18-pin DIL metal case, and operates over full military temperature range. (-55°C to +125°C), as well as the industrial (0 to +70°C) temperature range.
