OPA637BPG4, Precision High-Speed Difet Operational Amplifier, 8 Pin DIP, Quantity 2, Burr Brown/Texas Instruments. The OPA637 Difet operational amplifiers provide a new level of performance in a precision FET op amp. When compared to the popular OPA111 op amp, the OPA637 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 OPA637 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 OPA637 is stable in gains equal to or greater than five. 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. * VERY LOW NOISE: 4.5nV/sqrt(Hz) at 10kHz * FAST SETTLING TIME: 450ns to 0.01% -High Performance Audio Circuitry Click here to see the datasheet.
