ZHCS228A June 2011 – February 2024 OPA564-Q1
PRODUCTION DATA
The complex load impedances common in power op-amp applications can cause output-stage instability. For normal operation, output compensation circuitry is typically not required. However, if the OPA564-Q1 is intended to be driven into current limit, an R/C network (snubber) can be required. A snubber circuit, such as the one shown in Figure 8-10 can also enhance stability when driving large capacitive loads (greater than 1000pF) or inductive loads (for example, motors or loads separated from the amplifier by long cables). Typically, 3Ω to 10Ω in series with 0.01μF to 0.1μF is adequate. Some variations in circuit value can be required with certain loads.
