PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
Figure 9-1 shows the BUF634A connected as an open-loop buffer. The source impedance and optional input resistor, RS, influence the frequency response; see Figure 7-3. Bypass the power supplies with capacitors connected close to the device pins. Capacitor values as low as 0.1 µF assure stable operation in most applications, but high output current and fast output slewing can demand large current transients from the power supplies, requiring the use of solid tantalum 10-µF capacitors. High-frequency, open-loop applications benefit from special bypassing and layout considerations. See the Section 9.1.1 for more information. If the BUF634A input is left floating, the device output can swing to either of the supplies based on the input bias current polarity.
