芯片型号:A7030

功能特点

■The A7031 is Stereo audio power amplifier designed for demanding audio applications. It is capable of delivering 2*2.7 watt of continuous average power to a 4 BTL load with less than 1% distortion (THD+N) from a 5V battery voltage. It operates from 2.7V to 5.5V. To simplify audio system design, the A7031 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.

■Features like excellent RF-rectification immunity, higher PSRR, the advanced pop & click circuitry, a minimal count of external components and low-power shutdown mode make A7031 ideal for wireless handsets and other portable device.
