Description

The TPA186x series of amplifiers are the newest highsupply voltage amplifiers with 30-μV low offset, low noise,

and stable high-frequency response. They incorporate

3PEAK’s proprietary and patented design techniques to

achieve excellent AC performance with 6-MHz bandwidth,

5-V/μs slew rate, and low distortion while drawing only

1.4-mA quiescent current per amplifier. The input commonmode voltage range extends to V−, and the outputs swing

rail-to-rail.

The TPA186x has an over-temperature protection feature

to guarantee chip safety. The output of the TPA186x will

enter high impendence when the die temperature reaches

around 170°C and will recover the function when the die

temperature is down to around 150°C. The product has a

very small power temperature coefficient, which is helpful

to temperature-sensitive applications.
