APPLICATION INFORMATION

Operating Characteristics

The OPA365 amplifier parameters are fully specified from 2.2 V to 5.5 V. Many of the specifications apply from

−55°C to 125°C. Parameters that can exhibit significant variance with regard to operating voltage or temperature

are presented in Typical Characteristics.

General Layout Guidelines

The OPA365 is a wideband amplifier. To realize the full operational performance of the device, good

high-frequency printed circuit board (PCB) layout practices are required. Low-loss 0.1-

µF bypass capacitors must

be connected between each supply pin and ground as close to the device as possible. The bypass capacitor

traces should be designed for minimum inductance.

Basic Amplifier Configurations

As with other single-supply op amps, the OPA365 may be operated with either a single supply or dual supplies

(see Figure 2). A typical dual-supply connection is shown in Figure 2, which is accompanied by a single-supply

connection. The OPA365 is configured as a basic inverting amplifier with a gain of

−10 V/V. The dual-supply

connection has an output voltage centered on zero, while the single

−supply connection has an output centered
