IS31AP2036-CLS2-TR

Overview

The IS31AP2036-CLS2-TR is a Class-K audio power amplifier with integrated charge pump and automatic gain control. It operates from 3.0V to 5.0V over -40°C to +85°C in an FCQFN-16 package. The device delivers up to 2.0W into 8Ω at 4.2V, maintaining constant output power of 0.8W, 1.0W, or 1.2W via AGC. Key electrical parameters include 75% efficiency, 0.05% THD+N, -72dB PSRR, and 102µV output noise.

Feature Summary

Integrates high-efficiency charge pump for voltage boosting without external inductors
Advanced automatic gain control maintains stable output power during supply voltage drops
Fully differential design reduces RF noise and electromagnetic interference
Includes integrated pop-and-click suppression, thermal protection, and short-circuit protection

Applications

Smart phones
Cellular phones
PDAs
GPS devices
Portable electronics

Procurement Notes

Verify the manufacturer designation as Integrated Silicon Solution (ISSI) rather than Lumissil Microsystems, as the datasheet confirms ISSI origin. Confirm the specific suffix CLS2 corresponds to the FCQFN-16 lead-free package variant. Check current availability status as the component may be subject to end-of-life restrictions or limited stock conditions.

Selection Notes

Select this amplifier for portable applications requiring high efficiency and space-saving designs without inductors. The integrated charge pump allows driving higher power speakers from low-voltage batteries. Ensure input resistor matching is prioritized for optimal CMRR and PSRR performance. Verify that the operating temperature range meets the environmental requirements of the target application.

Part Context

This component belongs to the IS31AP2036 series of Class-K audio amplifiers. It is designed by Integrated Silicon Solution, Inc. The part number IS31AP2036-CLS2-TR specifically denotes the industrial temperature grade version packaged in FCQFN-16 with tape and reel shipping quantity.
