The NCP2993 is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The NCP2991 is capable of delivering 1.3 W of continuous average power to an 8.0 Ω BTL load from a 5.0 V power supply, and 1.1 W to a 4.0 Ω BTL load from 3.6V power supply. The NCP2991 provides high quality audio while requiring few external components and minimal power consumption. It features a low-power consumption shutdown mode, which is achieved by driving the /SD 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 differents Turn On times (15 ms or 30ms) adjustable with the TON pin. Due to its best-in-class 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 0.4 mm pitch (Lead-Free).
