require any compensation, but a proper power−supply
bypass is required as shown in Figure 24. Performance will
be enhanced by adding a filter capacitor (C2) to the
mid−supply node (pin 2). See Typical Performance
Characteristics for details.

THERMAL CONSIDERATIONS
temperature of the device (150°C). Figure 15 shows the
tradeoff between output power and junction temperature for
different areas of exposed PCB copper (2 oz). If the
maximum power is exceeded momentarily, normal circuit
operation will be restored as soon as the die temperature is
reduced. Leaving the device in an “overheated” condition
for an extended period can result in device burnout. To
ensure proper operation, it is important to observe the SOA
curves.

dramatically with a filter capacitor installed (see Typical
Performance Characteristics). In addition a C2 filter
capacitor at pin 2 will suppress start−up popping noise. To
insure optimal suppression the time constant of the bias
filtering needs to be greater than the time constant of the
input capacitive coupling circuit, that is C2 x 25 k > C1 x R1.
