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

The OPA358 is optimized for supply voltages from +2.7V to +3.3V, with an operating range of +2.5V to +3.6V. Quiescent current is only 5.2mA per channel.

In shutdown mode, the quiescent current is reduced to < 5µA, dramatically reducing power consumption. This is especially important in battery-operated equipment such as digital still cameras (DSCs) or mobile phones with integrated cameras.

The OPA358 is available in SC70-6, the smallest package currently available for video applications.
