Flash 16 ADC

Description

The Flash ADC is a complete data acquisition unit optimized for photoacoustic microscopy and scanning applications as the highest priority. The unit provides close to 100% duty cycle, a 125MS/s sampling rate, as well as 16-bit accuracy and a preamplifier. Key features include a noise-reducing variable gain amplifier, low power consumption, and compact size.
