ETK2011 Overview
Description
ETK2011 is a digital audio power amplifier IC with maximum output of 2.5W (RL=4Ω)×1ch. ETK2011 has a “Pure Pulse Direct Speaker Drive Circuit” which directly drives speakers while reducing distortion of pulse output signal and reducing noise on the signal, and realizes the highest standard low distortion rate characteristics and low noise characteristics among digital amplifier ICs for mobile use.
Key Features
- Also the nonclip output control function can adapt the output clip caused by power supply voltage down with battery
- This is the difference from the traditional AGC (Auto Gain Control) or ALC (Auto Level Control) circuit
- ETK2011 has the powerdown function which can minimize the power consumption in the standby state
