The recommended operating voltage range for the SA614AD-T is 4.5V to 16V, although it can operate up to 18V with reduced performance.
To ensure proper biasing, connect the midpoint of the differential input (pins 2 and 3) to a voltage equal to VCC/2 using a resistive divider network, and decouple the input pins with capacitors to ground.
The maximum input signal amplitude the SA614AD-T can handle is approximately 2.5V peak-to-peak differential signal, beyond which the amplifier may saturate or distort.
To minimize noise and interference, use a ground plane, keep the input and output traces short and shielded, and decouple the power supply lines with capacitors. Additionally, consider using a common-mode choke or ferrite bead to filter out high-frequency noise.
While the SA614AD-T is designed for differential input, it can be used as a single-ended amplifier by tying one input to ground and using the other input as the signal input. However, this configuration may compromise the amplifier's common-mode rejection ratio and noise performance.
