General Description
The AT1175 is a CMOS two-step A/D converter capable of digitizing full-scale analog input signals into 8-bit digital words at sample rate of 20 MSPS. For most application, no external sample-andhold or video driving amplifiers are needed thanks to the device’s narrow aperture time, wide bandwidth, and low input...
