3 Description
The OPA695 is a high bandwidth, current-feedback
operational amplifier that combines an exceptional
4300-V/μs slew rate and a low input voltage noise to
deliver a precision, low-cost, high dynamic range
intermediate frequency (IF) amplifier. Optimized for
high gain operation, the OPA695 is ideally suited to
buffering surface acoustic wave (SAW) filters in an IF
strip, or delivering high output power at low distortion
for cable-modem upstream line drivers. At lower
gains, a higher bandwidth of 1400 MHz is achievable,
making the OPA695 an excellent video line driver for
supporting high-resolution RGB applications.
The OPA695 low 12.9-mA 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 optional disable control pin. Leaving this pin
open, or holding it HIGH, gives normal operation. If
pulled LOW, the OPA695 supply current drops to less
than 170 μA. This power-saving feature, along with
exceptional single +5-V operation and ultra-small
SOT23-6 packaging, make the OPA695 ideal for
portable applications.
