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.

DATEL’s ADS-112 is a 12-bit, functionally com-

Typical applications include spectrum, tran-
