com FAN7024 675mW CMOS Mono Power Amplifier with Shutdown Description The FAN7024 is a bridge connected audio power amplifier capable of delivering 675mW of continuous average power to an 8Ω load with less than 0.
3%(THD) from a 5V power supply.
The FAN7024 requires few external components and operates on low supply voltage from 2.
3V to 5.
5V.
Since the FAN7024 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is ideally suited for low power portable systems that require minimum volume and weight.
The FAN7024 features an externally controlled gain and low power consumption shutdown mode (0.
1uA,typ.
).
Additional FAN7024 features include thermal shutdown protection, unity gain stability, and external gain set.
