ADA4097-1/ADA4097-2 PIN CONFIGURATIONS AND FUNCTION DESCRIPTIONS Figure 4. Pin Configuration for the ADA4097-1 6-Lead TSOT Table 6. Pin Function Descriptions for ADA4097-1 6-Lead TSOT Pin No. Mnemonic Description
1 VOUT Amplifier Output. 2 −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. 3 +IN Noninverting Input of the Amplifier. 4 −IN Inverting Input of the Amplifier. 5 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. 6 +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.
