Basic Configuration

Figure 8-1 shows the OPA564-Q1 connected as a basic noninverting amplifier. However, the OPA564-Q1 can be used in virtually any op-amp configuration.

Bypass power-supply pins with low series impedance capacitors. The technique of using ceramic and tantalum capacitors in parallel is recommended. Use power-supply wiring with a low series impedance.

1. RSET sets the current limit value from 0.4A to 1.5A.
2. E/S pin forced low shuts down the output.
3. VDIG must not exceed (V–) + 5.5V; see Figure 8-12 for examples of generating a signal for VDIG.
