Texas Instruments OPA684 Low-Power, Current Feedback Operational Amplifier With Disable OPA684IDBVTG4

The OPA684IDBVTG4 is a low-power, wideband current-feedback operational amplifier designed for applications requiring high performance. It features an internally closed-loop input buffer stage that enhances linearity and reduces harmonic distortion, achieving low distortion levels of less than -78 dBc at 5 MHz. The amplifier supports a bandwidth exceeding 120 MHz for gains greater than +10, making it suitable for high-gain applications without significant bandwidth interaction. This device operates on a single supply voltage ranging from +5V to +12V or dual supplies of ¬±2.5V to ¬±6V, with a low supply current of 1.7 mA and a shutdown current of only 100 ¬µA. The OPA684IDBVTG4 can deliver a full ¬±4V peak-to-peak output swing on ¬±5V supplies, with an output current capability of 120 mA, making it effective for driving loads such as broadcast video drivers and ADC input drivers. The operational amplifier is specified for a temperature range of -40¬8C to +85¬8C and is available in a SOT-23 package, which is suitable for compact designs. Its robust performance and low power consumption make it a viable choice for engineers looking for efficient amplification solutions in various applications.
