OPA3695中文资料具有禁用功能的超宽带电流反馈运算放大器数据手册TI规格书

描述 Description

The OPA3695 is a triple, very high bandwidth, current-feedback opamp that combines an exceptional 4300V/µs slew rate and a very high 900MHz bandwidth (G = +2V/V) to provide an amplifier that is ideal for the most demandingvideo applications. The device versatility is enhanced with a low 1.8nV/√Hz input voltage noise and an output stage that can swing within 1V from the supply rail to deliver a high dynamic range signal, making it well-suited for analog-to-digital converter (ADC) front-ends or digital-to-analog converter (DAC) output buffering. Optimized for high gain operation, the OPA3695 is also well-suited for buffering surface acoustic wave (SAW) filters in an intermediate frequency (IF) system.
The low 12.9mA/channel supply current is precisely trimmed at +25°C. This trim, along with a low temperature drift, gives low system power over temperature. System power may be further reduced using theDisable control pin. Leaving this pin open, or holding it high, gives normal operation. If pulled low, the OPA3695 supply current drops to 100µA/channel. This power-saving feature, along with exceptional single +5V operation, makes the OPA3695 a good fit for low-power applications that require very high performance.The OPA3695 is available in an SSOP-16package.
