Product Overview
The ADA4627-1BRZ-R7 is a high-speed, low-noise single-channel JFET op amp from Analog Devices built on proprietary iPolar® technology. With 1pA typical input bias current, 70µV typical offset voltage (200µV max for B-Grade), 19MHz bandwidth and 82V/µs slew rate, it delivers high precision and fast transient response. Packaged in 8-pin SOIC, it fits high-speed photodiode amplifiers, DAQ frontends and precision filter circuits for industrial instrumentation.
Core Advantages
Ultra-Low Bias & Offset
Picoamp-level bias current and tight B-grade offset tolerance, reducing signal distortion for high-impedance sensors.
High-Speed AC Performance
19MHz unity-gain bandwidth and fast slew rate for clean high-frequency signal reproduction.
Ultra-Low Noise
6.1 nV/√Hz noise density at 10kHz to retain weak tiny signal details.
High-Impedance JFET Input
Eliminates source loading, supporting direct connection to capacitive and resistive sensors.
