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.
