The OPA656 device combines a very wideband, unity-gain stable, voltage-feedback operational amplifier with a FET-input stage to offer an ultra high dynamic-range amplifier for Analog-to-Digital Converter (ADC) buffering and transimpedance applications. Extremely low DC errors give good precision in optical applications.
●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 7-nV/√Hz input voltage noise to achieve a very low integrated noise in wideband photodiode transimpedance applications.
●Broad transimpedance bandwidths are achievable given the OPA656 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.
