The AD8330 from Analog Devices is a broadband variable gain amplifier covering DC to 150 MHz. It offers a fully differential signal path, low‑noise operation (5 nV/√Hz at 1 MHz), and a linear gain range of 0 dB to 50 dB with optional gain extension via the VMAG pin.
The device is supplied in a 16‑lead LFCSP (3 mm × 3 mm) or QSOP package and operates from 2.7 V to 6 V with a typical quiescent current of 20 mA. It is rated for –40 °C to +85 °C and includes features such as automatic offset compensation, power‑down modes, and ESD protection. This manual is written in Japanese.
