E-CMOS ELN4890

The ELN4890 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1 watt of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V DC power supply. The ELN4890 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.

GENERAL DESCRIPTION

Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The ELN4890 features a low-power consumption shutdown mode, which is achieved by driving the shutdown pin with logic low. Additionally, the ELN4890 features an internal thermal shutdown protection mechanism. The ELN4890 contains advanced pop & click circuitry which eliminates noises which would otherwise occur during turn-on and turn-off transitions. The ELN4890 is unitygain stable and can be configured by external gain-setting resistors. Key Specification
