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
When EN is pulled to low, the supply current drops to 0.5µA, the amplifier is disabled and the output is driven to VSS.
Pulling EN to high enables the amplifier. When exiting shutdown, there is a 6µs delay before the amplifier output
becomes active.
Note: Because the output is actively driven to VSS in shutdown, any pullup resistor on the output causes a current
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.
