PRODUCT OVERVIEW
plete, sampling A/D converter that is packaged in
a space-saving 24-pin DDIP. Requiring ±15V and
+5V supplies, a minimum sampling rate of 1MHz
is achieved while only dissipating 1.3 Watts. The
ADS-112 digitizes signals up to Nyquist frequen-
cies. Models are available for use in either com-
mercial (0 to + 70°C) or military (–55 to +125°C)
operating temperature ranges.
sient, vibration and waveform analysis. This device
is also ideally suited for radar, sonar, video digitiza-
tion, medical instrumentation and highspeed data
acquisition systems.
