OPA2695IRGTT

双路，超宽带电流反馈运算放大器具有禁用 Dual, Ultra-Wideband, Current-Feedback OPERATIONAL AMPLIFIER with Disable

The OPA2695 is a dual, very high bandwidth, current-feedback op amp that combines exceptional 2900V/µs slew rate and low input voltage noise to deliver a precision, low-cost, high dynamic range intermediate frequency IF amplifier. The device has been optimized for high gain operation, and the pin outs of the two available packages QFN-16, SO-8 have been optimized to provide symmetrical input and output paths. This architecture makes the OPA2695 an ideal choice as a differential driver, such as for a high-speed analog-to-digital converter ADC.

The OPA2695 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 with the optional disable control pin. Leaving this pin open, or holding it high, gives normal operation. If pulled low, the OPA2695 supply current drops to less than 200µA/channel. This power-saving feature, along with exceptional single +5V operation, makes the OPA2695 ideal for portable applications. The OPA2695 is available in an SO-8 without disable package or QFN-16 package with disable.
