OPA627AP

The OPA627AP belongs to OPA627 difet operational amplifiers family which provides a new level of performance in a precision FET op amp. When compared to the popular OPA111 op amp, the OPA627 has lower noise, lower offset voltage, and much higher speed. It is useful in a broad range of precision and high speed analog circuitry. The OPA627 is available in plastic DIP, SOIC and metal TO-99 packages. Industrial and military temperature range models are available. The OPA627 is fabricated on a high-speed, dielectrically-isolated complementary NPN/PNP process. It operates over a wide range of power supply voltage- ±4.5V to ±18V. Laser-trimmed difet input circuitry provides high accuracy and low-noise performance comparable with the best bipolar-input op amps. High frequency complementary transistors allow increased circuit bandwidth, attaining dynamic performance not possible with previous precision FET op amps. The OPA627 is unitygain stable. Difet fabrication achieves extremely low input bias currents without compromising input voltage noise performance. Low input bias current is maintained over a wide input common-mode voltage range with unique cascode circuitry.

The features of OPA627AP can be summarized as (1)very low noise: 4.5nV/Hz at 10kHz; (2)fast settling time: OPA627-550ns to 0.01%; (3)low VOS : 100V max; (4)low drift: 0.8V/°C max; (5)low IB : 5pA max; (6)OPA627: unity-gain stable.

The absolute maximum ratings of OPA627AP are (1)supply voltage: ±18V; (2)input voltage range: +V S + 2V to V S 2V; (3)differential input range: Total V S + 4V; (4)power dissipation: 1000mW; (5)operating temperature M Package: 55°C to +125°C P, U Package: 40°C to +125°C; (6)storage temperature M Package: 65°C to +150°C P, U Package: 40°C to +125°C; (7)junction temperature M Package: +175°C P, U Package: +150°C; (8)lead temperature (soldering, 10s): +300°C; (9)SOlC (soldering, 3s): +260°C.
