Description

VOUT

Amplifier Output.

−VS

Negative Power Supply. In single-supply applications, the −VS pin is normally soldered to a low impedance ground plane. In split-supply

applications, bypass the −VS pin with a capacitance of at least 0.1 μF to a low impedance ground plane, as close to the −VS pin as possible.

+IN

Noninverting Input of the Amplifier.

−IN

Inverting Input of the Amplifier.

SHDN

Op Amp Shutdown. The threshold for shutdown is approximately 1 V above the negative supply. If the SHDN pin is hard tied to −VS or floating,

the amplifier is active. If the SHDN pin is asserted high (VSHDN > −VS + 1.5 V), the amplifier is placed in a shutdown state, and the output of the

amplifier goes to a high impedance state. If the SHDN pin is left floating, it is recommended to connect a small capacitor of 1 nF between the

SHDN pin and the −VS pin to prevent signals from the −IN pin from capacitively coupling to the SHDN pin.

+VS

Positive Power Supply. Bypass the +VS pin with a capacitance of at least 0.1 μF to a low impedance ground plane, as close to the +VS pin as

possible.
