OCA7237 - Multi-level Constant Output Power Class D Audio Amplifier

Download the OCA7237 datasheet PDF. This datasheet also covers the OCA7237-ORIENT variant, as both devices belong to the same multi-level constant output power class d audio amplifier family and are provided as variant models within a single manufacturer datasheet.

Description

The OCA7237 is a high efficiency filter-less ClassD audio power amplifier with Automatic Gain Control (AGC) technology and an integrated high efficiency charge pump boost power supply.

Features

  • high efficiency up to 81%, which helps extend battery life when playing audio. The AGC with multi-level constant output power technology helps designer to select suitable output power which match the speaker. The OCA7237 has a 47μVrms low output noise at gain=8V/V to improve the signal to noise ratio (SNR). The OCA7237 is available.

WWW.ORIENT-CHIP.COM Web:www.orient-chip.com 、 OCA7237 Multi-level Constant Output Power Class D Audio Amplifier ◆General Description The OCA7237 is a high efficiency filter-less ClassD audio power amplifier with Automatic Gain Control (AGC) technology and an integrated high efficiency charge pump boost power supply. The device constantly monitors output power and dynamically adjust internal gain to prevent long time overstress across the speaker. The integrated charge pump structure generates 5.9V supply for output stage of amplifier. It can deliver 1W (THD+N=1%) of continuous average power to an 8Ω load by a lithium/Ion battery. The OCA7237 features high efficiency up to 81%, which helps extend battery life when playing audio.
