NCP2892AFCT2G

NCP2892AFCT2G is a Low-NOISE, low distortion Audio Amplifier with a SINGLE-ENDED output. It is designed to drive 8 ohm, 4 ohm or bridged-tied load (BTL) speakers with its robust output stage. Its maximum output power is specified as 12W into 8 ohm loads and 19.2W into 4 ohm loads, allowing it to be used in home theatre, car audio, and audio systems. The device features a power saving ECO mode, and its low power consumption makes it ideal for battery-powered applications.

NCP2892AFCT2G is a two-stage amplifier with a two-pole band pass filter in the first stage. The first stage of the amplifier contains an NMOS device and an RC network to provide the gain control. The second stage is an inverted differential amplifier, it provides the current and voltage gain. The device\'s power-saving ECO mode can be enabled, or disabled using two pins on the device. When enabled, the ECO mode reduces the supply current of the amplifier by lowering the quiescent current of the amplifier.

The device features an advanced clock-synchronous power-down feature. When the output is disabled and the user has enabled the power down mode, the device enters a low-power state. Once the power-down mode is enabled, the device will automatically enter a low-power state, and can be woken up by a Rising Edge of the PWDN pin. This feature prevents the system from entering a deep sleep state, saving power.

The amplifier\'s thermal protection circuit is designed to protect the system against thermal runaways due to excessive heat dissipation. The device has a thermal compensation network built into the power-down logic, which adjusts the quiescent current based on the temperature of the device. This ensures a safe operating condition for the system even in harsh temperature conditions.

In addition, the device features a soft start function that prevents large inrush currents from impacting the system during power up. This is accomplished by increasing the output voltage gradually over a few milliseconds during startup and reduces the need for a slow start-up circuit and also minimizes audible mute pop noise.

The NCP2892AFCT2G is ideal for applications requiring high performance and low power consumption. It is designed to drive 8 ohm, 4 ohm or bridged-tied load (BTL) speakers, and its maximum output power is specified as 12W into 8 ohm and 19.2W into 4 ohm loads. Its power-saving ECO mode makes it a good choice for battery-powered applications, while its thermal protection and soft start features ensures a safe operating condition. The device also features an advanced clock-synchronous power-down, which can help save power in battery-powered applications.
