Running with a single supply voltage from 3V to 12V, these amplifiers feature a large output voltage swing and high output current capable of driving standard 150Ω loads. A low operating voltage makes TSH7x amplifiers ideal for use in portable equipment. The TSH71, TSH73 and TSH75 also feature standby inputs, each of which allows the op-amp to be put into a standby mode with low power consumption and high output impedance. This function allows power saving or signal switching/multiplexing for high-speed applications and video applications. To economize both board space and weight, the TSH7x series is proposed in SOT23-5, TSSOP and SO packages.
