Broad transimpedance bandwidths are achievable given the OPA656U/2K5 device’s high 230-MHz gain bandwidth product. As shown below, a –3-dB bandwidth of 1 MHz is provided even for a high 1-MΩ transimpedance gain from a 47-pF source capacitance.
Feature
- 500 MHz Unity-gain Bandwidth
- Low Input Bias Current: 2 pA
- Low Offset And Drift: ±250 μV, ±2 μV/°C
- Low Distortion: 74-dB SFDR at 5 MHz
- High-Output Current: 70 mA
- Low Input Voltage Noise: 7 nV/√Hz input voltage noise to achieve a very low integrated noise in wideband photodiode transimpedance applications.
