NCP2990FCT2GEVB

The NCP2990FCT2GEVB is an evaluation board for NCP2990 audio power amplifier. The NCP2990 is capable of delivering 1.3W of continuous average power to an 8.0ohm load from a 5.0V power supply, and 1W to a 4.0ohm load from a 3.6V power supply. The NCP2990 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 SHUTDOWN pin with logic low. For maximum flexibility, the NCP2990 provides an externally controlled gain (with resistors), as well as an externally controlled turn on time (with the bypass capacitor). Due to its excellent PSRR, it can be directly connected to the battery, saving the use of an LDO.

• External turn on time setting: 60ms (1uF bypass capacitor)
• Zero pop and click noise in case of a single ended audio input
• Ultra low current shutdown mode: 10nA
• 2.2V to 5.5V operation
• Up to 1.0nF capacitive load driving capability
• Thermal overload protection circuitry
