1. OVERVIEW
The S3F401F has a 12-bit ADC. It converts the analog input signal into 12-bit binary digital codes at a maximum
sampling rate of 4MHz. The device is a monolithic ADC with on-chip, which consists of three sample and hold
amplifiers, four multiplying DACs, five sub-ranging flash ADCs and current reference. Normal speed of input is
below 100kHz which can be quantized by 4MHz clock.
