IS31AP4088A-QFLS2-EB: 2.84W x 2 @ 4Ω, 2.7 ~ 5.5V in

The IS31AP4088A evaluation board is a fully assembled and tested PCB that uses the IS31AP4088A Class-AB combining dual bridge speaker amplifiers and stereo headphone amplifiers on one chip. Designed to drive speaker impedance of 4Ω or larger. The evaluation board provides dual BTL output, capable of delivering 2.84W into a 4Ω speaker at 5V supply.

The IS31AP4088A is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.84W to a 4Ω load.

To simplify audio system design, the IS31AP4088A combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.

The IS31AP4088A features a low-power consumption shutdown mode and thermal shutdown protection. It also utilizes circuitry to reduce “clicks and pops” during device turn-on.
