AD8336: General Purpose 70 MHz, DC Coupled VGA

The AD8336 is a low noise single ended linear-in-dB, general purpose variable gain amplifier usable as a low noise variable gain element over a large supply voltage range. For example, at ±5 V supplies, the part can be used for frequencies up to 70 MHz (2 V p-p); the -3 dB bandwidth is 100 MHz; these values are for the lowest gain range (-14 to +46 dB). It operates on a wide power supply range of ±3 V to ±12 V.

The VGA has 60 dB of gain range and is intended for a broad spectrum of applications. Excellent bandwidth uniformity is maintained across the entire range. The gain control interface provides precise linear-in-dB scaling of 50 dB/V. Since the gain control input is differential it is easy to interface the gain control voltage to a variety of external circuits as long as they are within the devices' common voltage range.

The operating temperature range is -40°C to +125°C. The AD8336 is available in a 16-lead LFCSP (44 mm).
