The recommended operating voltage range for the SA614AD is 4.5V to 16V, with a typical voltage of 12V.
To ensure proper biasing, connect the VCC pin to a stable voltage source, and decouple it with a 10uF capacitor to ground. Also, connect the VEE pin to a stable negative voltage source or ground, depending on the application.
The maximum input signal amplitude that the SA614AD can handle is ±10V, with a typical input impedance of 1kΩ.
To reduce noise and oscillations, use a low-pass filter at the input, and ensure proper decoupling of the power supply lines. Additionally, use a ground plane and keep the layout as compact as possible to minimize parasitic inductances.
Yes, the SA614AD can be used as a voltage-controlled amplifier by applying a control voltage to the VCTRL pin. The gain of the amplifier will vary in response to the control voltage.
