Typical Application (continued)
V_CL+ and V_CL– are inputs that limit the output voltage swing of the amplifier. The voltages applied set an absolute
limit on the voltages at the output. Input voltages at V_CL+ and V_CL– clamp the output, ensuring that neither output
exceeds those values.
The power-down input is a TTL compatible input, referenced to the negative supply voltage. A logic low puts the
THS7530-Q1 device in power-saving mode. In power-down mode the part consumes less than 1-mA current, the
output goes high impedance, and a high amount of isolation is maintained between the input and output.
Power-supply bypass capacitors are required for proper operation. A 6.8-µF tantalum bulk capacitor is
recommended if the amplifier is located far from the power supply and may be shared among other devices. A
ceramic 0.1-µF capacitor is recommended within 0.1-in of the device power pin. The ceramic capacitors should
be located on the same layer as the amplifier to eliminate the use of vias between the capacitors and the power
pin.
