EUA2510 General Description
The EUA2510 integrates a boost converter with a high efficiency mono, Class D audio power amplifier to provide 1.2W continuous power into an 8 speaker when operating on a 3.3V power supply with boost voltage (PV1) of 5.0V. When operating on a 3.3V power supply, the EUA2510 is capable of driving a 4 speaker load at a continuous average output of 1.7W with less than 1% THD+N. The Class D amplifier is a low noise, filterless PWM architecture that eliminates the output filter, reducing external component count, board area consumption, system cost, and simplifying design.
The EUA2510's switching regulator is a current-mode boost converter operating at an adjust frequency of 0.62MHz and 1.25MHz.
The EUA2510 is designed for use in mobile phones and other portable communication devices. The high (88%) efficiency extends battery life when compared to Boosted Class AB amplifiers. The EUA2510 features a low-power consumption shutdown mode. Shutdown may be enabled by driving the Shutdown pin to a logic low (GND).
The gain of the Class D is externally configurable which allows independent gain control from multiple sources by summing the signals. Output short circuit and Thermal shutdown protection prevent the device from damage during fault conditions. Superior click and pop suppression eliminates audible transients during power-up and shutdown.
EUA4890 General Description
The EUA4890 is an audio power amplifier designed for portable communication device applications such as mobile phone applications. The EUA4890 is capable of delivering 1.0W of continuous average power to an 8 BTL and with less than 1% distortion (THD+N) from a 5.0V power supply, and 350mW to a 8 BTL load from a 3V power supply.
The EUA4890 provides high quality audio while requiring few external components and minimal power consumption. It features a low-power shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low.
The EUA4890 contains circuitry to prevent from "pop and click" noise that would otherwise occur during turn-on and turn-off transitions.
For maximum flexibility, the EUA4890 provides an externally controlled gain (with resistors), as well as an externally controlled turn-on and turn-off times (with the bypass capacitor).
The EUA4890 is available in a MSOP-8 , 3mm*3mm DFN package.
