The
OPA695 is a low-power, current-feedback amplifier that offers
unmatched bandwidth and slew rate at low and high gains. Featuring
1.4GHz bandwidth (G=+2) and 2500V/µs slew rate, it provides
exceptional pulse fidelity through the highest pixel update
rates—an excellent choice for the highest speed video
line driver applications. For Intermediate Frequency (IF) applications,
the OPA695 shows its versatility by offering 450MHz bandwidth
(G=±8) and 4300V/µs while maintaining precision performance.
Capable of +5V to +12V single-supply operation, the OPA695 provides
an improved output 3rd-order intercept at lower power than previous
IF amplifiers. The OPA695 is also ideal for cable modems, wireless
communications, portable instruments, test and measurement instrumentation
and many other applications.

Broadband
Video Line Driver: The combined capabilities
of 1.4GHz BW at a gain of +2V/V with 2900V/µs
results in a 0.8ns rise time for a 2V output
step-ideal for the highest speed video requirements.
Precision
IF Amplifier: At higher gains (±8V/V),
the OPA695 holds its performance by offering
low input voltage noise and 450MHz BW.
Other Applications include: Cable modems,
portable instruments, wireless communications
and test instrumentation. |

The OPA695 is an ideal amplifier to support data converters
such as TI's ADS5500 14-bit, 125-MSPS ADC and DAC5686 16-bit,
500-MSPS dual DAC. Additional products supporting wireless communications
and other high-speed applications include TI's high-performance
TMS320C6000™ and TMS320C5000™ DSP platforms, as
well as the GC5016 digital up/down converter functioning as
a preprocessor in DSP-based communications systems.
