OPA358 3 V Single Supply 80 MHz High-Speed Op-Amp

Texas Instruments' high-speed OPA358 amplifier is optimized for 3 V single-supply operation. The output typically swings within 5 mV of GND with a 150 Ω load connected to GND. The input common-mode range includes GND and swings to within 1 V of the positive power supply. The OPA358 offers excellent video performance of 0.5 dB gain flatness is 25 MHz, differential gain is 0.3%, and differential phase is 0.7°.

The OPA358 is optimized for supply voltages from +2.7 V to +3.3 V, with an operating range of +2.5 V to +3.6 V. The quiescent current is only 5.2 mA per channel and in shutdown mode, it is lowered to less than 5 µA, dramatically reducing power consumption. This is important in battery-operated equipment including digital still cameras (DSCs) and mobile phones with integrated cameras.

The OPA358 is available in SC70-6, an ultra-small package for video applications.
