IS31AP2121 Datasheet 2×25w Stereo / 1× 50w Mono Digital Audio Amplifier

Manufacturer: ISSI (now Infineon)

Overview: IS31AP2121 2×25W STEREO / 1× 50W MONO DIGITAL AUDIO AMPLIFIER WITH 20 BANDS EQ FUNCTIONS, DRC AND 2.

General Description

The IS31AP2121 is a digital audio amplifier capable of driving 25W (BTL) each to a pair of 8Ω speakers and 50W (PBTL) to a 4Ω speaker operating at 24V supply without external heat-sink or fan.

The IS31AP2121 is also capable of driving 4Ω, 12W (SE)×2 + 8Ω, 25W (BTL)×1 at 24V supply for 2.1CH application.

The IS31AP2121 can provide advanced audio processing functions, such as volume control, 20 EQ bands, audio mixing, 3D surround sound and Dynamic Range Control (DRC).

Key Features
