APPLICATION NOTE
TA7709P/F
1. Input signals can be applied between pin0) or and pin@ as common without input coupling
capacitors.
In case that input signals is applied between pin0) or and GND terminal, it is necessary that
connecting input coupling capacitors, and starting time of amplifiers will increase.
2. Test pin© and (E) should not be connected to avoid malfunctions.
3. Ripple rejection characteristics are shown in the attached paper. To keep good rejection ratio, a
combination of the TA7709P, TA7709F and the TA7688F is recommendable.
In this case, the VCC of the TA7709P, TA7709F is supplied by VRF output of the TA7688F.
