GENERAL DESCRIPTION
The SPT1175 is a CMOS two-step A/D converter capable of
digitizing full scale analog input signals into 8-bit digital words
at a sample rate of 20 MSPS.
For most applications, no external sample-and-hold or
video driving amplifiers are required due to the device's
narrow aperture time, wide bandwidth, and low input ca-
pacitance.
The SPT1175 operates from a single +5.0 V 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-compat-
ible. The SPT1175 is ideal for most video and image pro-
cessing applications that require low power dissipation and
low cost. The SPT1175 is available in 24-lead plastic SOIC,
plastic DIP, and PLCC packages over the commercial tem-
perature range (0 to +70
°
C). It is also available in die form.
