DESCRIPTION
●The OPA656 combines a very wideband, unity-gain stable voltage-feedback op amp with a FET-input stage to offer an ultra high dynamic-range amplifier for ADC (Analog-to-Digital Converter) buffering and transimpedance applications. Extremely low DC errors give good precision in optical applications.
