Product Innova tionFrom
until reaching pin 6.Connect all Vcc power supply and input signal related ground connections to ANALOG
GND keeping conductors separate until reaching pin 1. Do not allow ground loops toform by making additional
ground connections at the low side of the physical power supplies. If ground plane is used do not allow more
than 1mA to flow through it.
3. Beware of capacitive coupling between output connections and signal inputs through the parasitic capacitance
between layers in multilayer PCB designs.
4. Do not run small signal traces between the pins of the output section (pins 8-12).
CURRENT SENSE
There are two load current sensing pins, I SENSE A and I SENSE B. The two pins can be shorted to POWER GND
in the voltage mode connection but both must be used in the current mode connection. It is recommended that
R SENSE resistors be non-inductive. Load current flows in the I SENSE pins. The SA60 has no internal current
limit.
TRANSIENT SUPPRESSION
An RC network of a 100 pF Capacitor and a one ohm resistor is required as shown in the external connection dia-
gram on page 1. This network assures proper operation under various loads. Minimal power is dissipated in the
resistor.
