The OPA820SKGD3 is an integrated circuit power amplifier manufactured by Texas Instruments used for instrumentation, operational amplifiers (op-amps), buffer amplifiers and linear amplifiers. It is an ultra high-speed current-feedback amplifier which is suitable for a variety of applications from video to communications, from audio to automotive, and from aerospace to optoelectronics.

The OPA820SKGD3 has an input voltage range of 2.3V to 12V with a power consumption of 2.47W. It has a wide-band frequency response of up to 80MHz and a large amount of gain – up to 72 dB of power gain. The device is rated for 8-Ohm loads and can drive up to 8 Ohm loads. Its low offset voltage ensures a low distortion output when used with AC signals.

The OPA820SKGD3 is designed to be used in a range of applications. It is an ideal device for use in video applications where wide video bandwidths and low distortion are important, such as a video camera or a video amplifier. It is also suitable for a wide range of audio and communications applications such as amplifiers for radio receivers, high-speed transceivers and switch-mode amplifiers.

The OPA820SKGD3 works using a current-feedback amplifier (CFA). This type of amplifier is used to provide a high output voltage, without distortion, regardless of input voltage changes. This type of amplifier has a high speed rise and fall times and is not prone to oscillation. A CFA incorporates a voltage-controlled current source (VCCS) as its input stage. The VCCS ensures that the input current remains constant with varying input voltage. The VCCS is then connected to the output stage, which is responsible for providing the voltage amplification.

The OPA820SKGD3 is designed to provide a high-speed, wide frequency response, with low distortion and low power consumption. It is designed to be used in a variety of applications, such as video and audio, communications, automotive, and aerospace. Its low noise and high power gain make it an ideal device for use in these and other applications. Due to its capability for high performance at low cost, it is a widely used device in many fields.
