TSH330: 1.1GHz High-Speed Op-Amp

Very wide bandwidth and excellent linearity are increasingly necessary for
high-end equipment. The TSH330, with a 1.1 GHz bandwidth, is part off ST’s new TSH3x series of high-speed operational amplifiers.

The TSH330, designed with an advanced BiCMOS process, marries the benefits of high performance with the price advantages of high volume production.

By combining a current feedback architecture with a very high-speed complementary technology, the TSH330 can provide a large bandwidth of 1.1GHz on only 16mA of quiescent current.

This amplifier demonstrates a 0.1dB gain flatness up to 160-MHz at gain=2, and a high slew rate of 1800V/µs is provided, with only 1.3nV/Hz of input-voltage noise.

With an output stage optimized for driving video or instrumentation lines, the TSH330 demonstrates very good linearity: -78dBc versus 10MHz/2Vpp on 100 Ohm load and
-73dBc versus 20MHz/2Vp-p on 100 Ohm load.
