Description
The TPA268X series amplifiers are newest high supply voltage
amplifiers with low noise and high frequency response. They
incorporate 3PEAK’s proprietary and patented design
techniques to achieve very good AC performance with 20MHz
bandwidth, 10V/μs slew rate and low distortion while drawing
only 6mA of quiescent current per amplifier.
The combination of features makes the TPA268X ideal choices
for industrial control, motor control and audio amplification,
sound ports, and other consumer audio.
