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.
