Optimized for • Ultra-High Slew Rate: 4300 V/ μs high gain operation, the OPA695 is ideally suited to • 3RD-Order Intercept: > 40 dBm (f < 50 MHz) buffering surface acoustic wave (SAW) filters in an IF • Low Power: 129 mW strip, or delivering high output power at low distortion for cable-modem upstream line drivers. At lower • Low Disabled Power: 0.5 mW gains, a higher bandwidth of 1400 MHz is achievable, • Packages: SOIC-8, VSSOP-8, SOT23-6 making the OPA695 an excellent video line driver for supporting high-resolution RGB applications. 2 Applications The OPA695 low 12.9-mA supply current is precisely • Very Wideband ADC Drivers trimmed at +25°C. This trim, along with a low • Low-Cost Precision IF Amplifiers temperature drift, gives low system power over • Broadband Video Line Drivers temperature. System power may be further reduced using the optional disable control pin. Leaving this pin • Portable Instruments open, or holding it HIGH, gives normal operation. If • Active Filters pulled LOW, the OPA695 supply current drops to less • ARB Waveform Output Drivers than 170 μA. This power-saving feature, along with exceptional single +5-V operation and ultra-small • OPA685 Performance Upgrades SOT23-6 packaging, make the OPA695 ideal for portable applications.
