Low Distortion, Low Noise OpAmp Burr-Brown / Texas Instruments The high unity-gain stable bandwidth and JFET input allows exceptional performance in high-speed, low-noise integrators. The high input impedance and low bias current provided by the FET input is supported by the ultra-low 7nV/rtHz input voltage noise to achieve a very low integrated noise in wideband photodiode transimpedance applications. Broad transimpedance bandwidths are achievable given the OPA656’s high 230MHz gain bandwidth product. As shown below, a –3dB bandwidth of 1MHz is provided even for a high 1Mohm transimpedance gain from a 47pF source capacitance. * 500MHz UNITY-GAIN BANDWIDTH * LOW INPUT BIAS CURRENT: 2pA * LOW OFFSET AND DRIFT: ±0.25mV, ±2µV/°C * LOW DISTORTION: 74dB SFDR at 5MHz * LOW INPUT VOLTAGE NOISE: 7nV/rtHz * WIDEBAND PHOTODIODE AMPLIFIERS * SAMPLE-AND-HOLD BUFFERS * WIDEBAND PRECISION AMPLIFIERS * TEST AND MEASUREMENT FRONT ENDS US: $3.75 Canada: $4.50 International: $5.50 Lowest cost option. 2-nd item: S&H 75% less than first (or 25% of first) items 3-5: S&H 80% less than first (or 20% of first) items 6-10: S&H 90% less than first (or 10% of first) Be sure to add me to your favorites list!
