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-and-
hold or video driving amplifiers are needed
thanks to the device’s narrow aperture time,
wide bandwidth, and low input capacitance.
The AT1175 operates from a single +5.0V power
supply and has an internal voltage reference,
which eliminates the need for external reference
circuitry. All digital inputs are CMOS
compatible and the tri-state outputs are TTL-
compatible. The AT1175 is ideal for most video
and image processing applications that require
low power dissipation and low cost.
