Overview
The TPA178x family is the newest high supply voltage amplifiers with low offset, low power, and stable highfrequency response. These devices incorporate the proprietary and patented design techniques of the 3PEAK to achieve very good AC performance with 10-MHz bandwidth, 20-V/μs slew rate, and low distortion while drawing only 2000 μA of quiescent current per amplifier. The input common-mode voltage range extends to V– and V+, and the outputs swing rail-to-rail. The TPA178x family can be used as plug-in replacements for many commercially available op-amps to reduce power and improve the range and performance of the input and output.
