ADAU1590ACPZ-RL7

Overview

The ADAU1590ACPZ-RL7 is a two-channel, bridge-tied load (BTL) switching audio power amplifier with an integrated Σ-Δ modulator. It operates from a PVDD supply of 9 V to 15 V and logic supplies of 3.0 V to 3.6 V. The device delivers up to 12.5 W into a 4 Ω load at 1% THD+N. Key electrical parameters include 0.005% THD+N, 101 dB dynamic range, and >55 dB PSRR. It features programmable gain amplification (PGA) settings of 0 dB, 6 dB, 12 dB, and 18 dB.
