BUF01900AIDRCT Application Field and Working Principle

The BUF01900AIDRCT is an integrated Linear amplifier module designed for general-purpose video applications. The device consists of two independent NMOS common source functioning amplifiers and is designed for use in applications such as analog video amplifiers, video signal processing, video signal generators, and medical video applications.

Application Field

The BUF01900AIDRCT is specifically designed for applications where wide bandwidth performance, low voltage operation, and high linearity are required. The module measures in at just 6.60 x 7.15 mm and offers video output voltage ranges of 10-20Vp-p. The module’s wide bandwidth signal conditioning architecture enables applications such as medical video amplifiers, video scalers, and signal processing applications. Medical video applications include surgical imaging systems, CT systems, and cardiac ultrasound. Video signal processing applications include Cd/Cd-Video signal conditioning, Video signal conditioning, VCR/DVR signal conditioning, and signal conditioning for various multimedia systems.

Working Principle

The BUF01900AIDRCT operates by operating two independent NMOS common source amplifiers configured in series. Each amplifier exhibits transistor gain of slightly over 40db. The first amplifier applies EMI filtering, creates a small differential voltage swing on the input signal, then amplifies the signal and applies EMI attenuation. The second amplifier then takes the signal, amplifies it, and applies additional filtering to reduce EMI-generated noise.

This two-stage amplification process yields an overall gain of approximately 80db and offers video output voltage ranges of 10-20Vp-p. The device also employs current-limited and open-circuit output protection to improve device reliability. In addition, the device offers a wide operating range from 0.9 to 1.3V and a supply current of only 16 mA.

Conclusion

The BUF01900AIDRCT linear amplifier module is designed to deliver wide bandwidth and low voltage operation, enabling it to be used in applications such as medical video amplifiers, video scalers, and signal processing applications. The device employs two independent NMOS common source amplifiers configured in series, resulting in an overall gain of approximately 60 dB and wide video output voltage ranges. In addition, the device offers current-limited and open-circuit output protection to improve device reliability.
