Overview
The OPA830IDBVR is a low-power, single-supply, wideband operational amplifier designed by Texas Instruments. This amplifier is optimized for operation on a single +3V or +5V supply, although it can also operate on ±5V or +10V supplies. It features a high bandwidth of 250MHz at a gain of +1 and 110MHz at a gain of +2, making it suitable for a variety of high-frequency applications. The OPA830IDBVR is known for its low supply current of 3.9mA at +5V, high slew rate of 550V/µs, and low input voltage noise of 9.2nV/√Hz, ensuring low distortion and wide dynamic range operation.
