TPA1861

40-V, 6-MHz, Zero-Drift Op Amps

Overview

The TPA186x series of amplifiers are the newest high-supply 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 common-mode 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.
