These amplifiers also feature large output voltage swing and high output current capability to drive standard 150Ω loads. Running at single or dual supply voltage from 4.5V to 12V, these amplifiers are tested at 5V (±2.5V) and 10V (±5V) supplies. The TSH81 also features a standby mode, which allows the operational amplifier 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. For board space and weight saving, the TSH8x series is proposed in SOT23-5, TSSOP8 and SO-8 plastic micropackages.
