IS31AP2036A-CLS2-TR

Overview

The IS31AP2036A-CLS2-TR is a Class-K audio power amplifier with integrated charge pump and automatic gain control. It delivers up to 2.0W into an 8Ω load at 4.2V supply, achieving 75% efficiency. Operating from 3.0V to 5.0V, it features low EMI, -66dB PSRR, and 0.05% THD+N. The device includes thermal AGC, pop-and-click suppression, and Pulse Count Control for mode selection. Packaged in FCQFN-16 (2mm × 2mm), it operates between -40°C and +85°C.

Feature Summary

Integrates high-efficiency charge pump converter eliminating external inductors
Advanced automatic gain control maintains constant output power during voltage drops
Fully differential design reduces RF noise and electromagnetic interference
Includes integrated thermal protection, short-circuit protection, and click-and-pop suppression

Applications

Smart phones
Cellular phones
Portable electronics

Procurement Notes

Verify the specific ordering suffix CLS2 against the manufacturer's current datasheet to confirm package type and reel quantity specifications. Ensure compatibility with the FCQFN-16 footprint and lead-free requirements. Confirm that the industrial temperature range meets system operational needs before finalizing procurement orders.

Selection Notes

Select this component for portable devices requiring high audio output power within a small form factor. The absence of inductors simplifies PCB layout compared to traditional Class-D amplifiers. Consider the Pulse Count Control interface for mode switching if GPIO resources are limited. Verify input resistor matching to optimize CMRR and PSRR performance.

Part Context

This part belongs to Lumissil Microsystems' IS31AP series of audio power amplifiers. It utilizes Class-K topology to combine the efficiency of switching amplifiers with the linearity of linear amplifiers. The series targets mobile consumer electronics where battery life and acoustic quality are critical constraints.
