The OPA890 is a low power, wideband voltage feedback operational amplifier designed for applications requiring high performance and efficiency. It operates with a flexible supply range of +3V to +12V for single supply and ¬±1.5V to ¬±6V for dual supplies. The amplifier features a high slew rate of 500 V/Oºs and a bandwidth of 115 MHz at a gain of +2 V/V, making it suitable for high-speed applications. It can deliver an output voltage swing of ¬±4V with a drive current exceeding 35 mA. The OPA890 is unity-gain stable and offers low quiescent current of 1.1 mA, which can be further reduced to less than 30 OºA when the disable pin is activated. This makes it ideal for battery-powered devices and portable instruments. The device is also characterized by low input offset voltage and low noise, ensuring high precision in signal processing. Applications include video line driving, ADC input buffering, and high-speed imaging channels. The OPA890 is available in various package options, including SOT23-6 and SO-8, and operates over a temperature range of -40¬8C to +85¬8C.
