NCP2993
NCP2993 is Audio Power Amplifier manufactured by onsemi.
features a low
- power consumption shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low.
The NCP2993 contains circuitry to prevent from “pop and click” noise that would otherwise occur during turn- on and turn- off transitions. It is a zero pop noise device when a single ended or a differential audio input is used.
For maximum flexibility, the NCP2993 provides an externally controlled gain (with resistors). In addition, it integrates 2 different Turn On times (15 ms or 30 ms) adjustable with the TON pin.
Due to its superior PSRR, it can be directly connected to the battery, saving the use of an LDO.
This device is available in a 9- Pin Flip- Chip CSP package with a 0.4mm pitch (Lead- Free).
