OP285GSZ-REEL7

OP285 is a precision high-speed amplifier featuring the butler amplifier front-end. This new front-end design combines the accuracy and low noise performance of bipolar transistors with the speed of JFETs. This yields an amplifier with high slew rates, low offset and good noise performance at low supply currents. Bias currents are also low compared to bipolar designs. Typical applications include high performance audio, active filters, fast amplifiers and integrators.

• Low offset voltage is 250μV max at Vs = ±15V
• Low noise is 6nV/√Hz at f = 1KHz, Vs = ±15V
• Low distortion is 0.0006%
• High slew rate is 22V/μs at RL = 2Kohm, Vs = ±15V
• Wide bandwidth is 9MHz at Vs = ±15V
• Low supply current is 5mA at Vs = ±15V
• Low offset current is 2nA typ at Vs = ±15V
• Unity-gain stable
• 8 lead NSOIC package
• Operating temperature range from -40°C to 85°C
