Replace AD811JRZ, GXSC High Performance OPA GX811JRZ for Video Line Driver

A variety of video signal processing and transmission systems need to use high-speed broadband operational amplifiers to achieve the high-speed video signal buffer amplification or modulation processing and other functions, operational amplifiers are one of the key parts of the video signal processing system. Video signal processing applications require operational amplifiers with wide bandwidth, high conversion rate, low distortion, large output current and other characteristics.

GXSC high-performance operational amplifier GX811JRZ is very suitable for high-speed pulse applications, can replace the AD811JRZ to meet the requirements of the video line drive.GX811JRZ is a wideband current feedback operational amplifier, -3dB bandwidth of 120MHz, gain of +2, differential gain and phase of 0.01% and 0.01 ° (RL = 150Ω ), making the GX811JRZ an excellent choice for video systems.

Design features of the GX811JRZ (AD811JRZ compatible):

1.The GX811JRZ (AD811JRZ compatible) has a rated supply voltage range of ±5V to ±18 and an operating temperature range of -40°C to +85°C with a maximum junction temperature of 155°C. The GX811JRZ is designed to be used in a wide range of applications, including video systems.

2.GX811JRZ (compatible with AD811JRZ) can achieve a maximum voltage swing rate of more than 2500V/μs, 2V step when 0.1% of the build-up time is less than 25ns, 10V step when 0.01% of the build-up time is less than 65ns.

3. The GX811JRZ (compatible with AD811JRZ) is ideal for use as an ADC or DAC buffer in a data acquisition system because it has low distortion and wide unit gain bandwidth up to 10MHz.

4. The GX811JRZ (AD811JRZ compatible) is a current feedback amplifier: it has a wide bandwidth, low voltage and current noise of 1.9nV/√Hz and 20pA/√Hz, respectively, and low input distortion voltage for wide dynamic range applications.

5. 35MHz bandwidth (G=+2); 0.1dB gain flatness specification; smaller differential gain and phase error, and this performance can be achieved under low power supply low current supply, whether driving one or two 75Ω cables.

For video load driving applications, the GX811JRZ (compatible with the AD811JRZ) is used to provide excellent performance at closed-loop gains of +1 or higher. Another important consideration when driving multiple cables is high-frequency isolation between the cable outputs. Due to the low output impedance, the GX811JRZ achieves better than 40dB at 5MHz when driving 75Ω cables.

In summary, the GXSC operational amplifier GX811JRZ (compatible with AD811JRZ) is well suited for applications in video circuits, and GXSC can provide professional technical services and stable supply support.
