OPA687U

The OPA687U is a kind of operational amplifier. The device combines a very high gain bandwidth and large signal performance with an ultra-low input noise voltage while dissipating only 18mA supply current. Where power savings is paramount, the device also includes an optional power down pin that, when pulled low, will disable the amplifier and decrease the quiescent current to only 1% of its powered up value. The typical applications include: (1)low distortion ADC driver; (2)OC-3 fiber optic receiver; (3)low noise differential amplifiers; (4)equalizing receivers; (5)ultrasound channel amplifiers; (6)improved replacement for the CLC425. It is available in rails.

There are some features of OPA687U: (1)high gain bandwidth: 3.8GHz; (2)low input voltage noise: 0.95nV/Hz; (3)very low distortion: -955dBc (5MHz); (4)low disabled power: 2mW; (5)very high slew rate: 900V/s; (6)stable for G12.

What comes next is the absolute maximum ratings of OPA687U: (1)power supply: ±6.5 VDC; (2)differential input voltage: ±1.2 V; (3)input voltage range: ±VS V; (4)storage temperature range: -40 to +125; (5)lead temperature (soldering, 10s): +300; (6)junction temperature (TJ): +175; (7)thermal resistance, junction to ambient, JA: 125/W typ.
