DESCRIPTION

The OPA3695 is a triple, very high bandwidth,

current-feedback op amp that combines an

exceptional 4300V/ms slew rate and a very high 900MHz bandwidth (G = +2V/V) to provide an

amplifier that is ideal for the most demanding video

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 the Disable control pin. Leaving this pin open,

or holding it high, gives normal operation. If pulled

low, the OPA3695 supply current drops to 100mA/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-16 package.
