Built on the proprietary next-generation SiGe bipolar process, it achieves 1 nV\/\u221aHz input voltage noise and 2.8 pA\/\u221aHz current noise while consuming only 3 mA per amplifier. With 230 MHz -3 dB bandwidth at G=+1, 120 V\/\u03bcs slew rate, and 45 ns settling time to 0.1%, the device is purpose-built for applications demanding high dynamic range, precision, and speed. The spurious-free dynamic range reaches -80 dBc at 2 MHz. The rail-to-rail output stage and wide 3 V to 10 V supply range provide maximum flexibility in low-voltage and battery-powered designs.","working_principle":"The ADA4896-2 employs a voltage feedback architecture fabricated on Analog Devices' proprietary SiGe bipolar process. (1) Input Stage: A differential pair using SiGe HBT transistors delivers ultra-low voltage noise (1 nV\/\u221aHz) and low 1\/f noise corner, critical for precision low-frequency signal processing. (2) Gain Stage: A high-gain transimpedance stage with compensation provides the 230 MHz bandwidth and 120 V\/\u03bcs slew rate, ensuring minimal signal distortion at high frequencies. (3) Output Stage: A rail-to-rail Class AB push-pull output enables output swings to within millivolts of the supply rails, maximizing usable dynamic range in single-supply systems. (4) Bias Network: A precision bias circuit maintains stable 3 mA per-amplifier quiescent current over temperature and supply variations, ensuring consistent performance.","pin_description":"
