AS1713

Data Sheet - A p p l i c a t i o n I n f o r m a t i o n

Note:

The absolute maximum ratings (see page 3) for power dissipation and output short-circuit duration (10s, max)

must be adhered since the output current can exceed 200mA (see Typical Operating Characteristics on page

6).

Shutdown

Pulling EN to high enables the amplifier. When exiting shutdown, there is a 6µs delay before the amplifier output

becomes active.

Note:

drain from the supply.

Power-Up

The AS1713 typically settle within 5µs after power-up.

Power Supplies and Layout

The AS1713 can operate from a single 2.7V to 5.5V supply or from dual ±1.35V to ±2.5V supplies. Good design

improves device performance by decreasing the amount of stray capacitance at the op amp inputs/outputs.

!

For single-supply operation, bypass the power supply with a 0.1µF ceramic capacitor.

!

For dual-supply operation, bypass each supply to ground.

!

Decrease stray capacitance by placing external components close to the op amp pins, minimizing trace and lead

lengths.
