GENERAL DESCRIPTION

DATEL's ADS-118 and ADS-118A are 12-bit, 5MHz, sampling

A/D converters packaged in space-saving 24-pin DDIP’s. The

ADS-118 offers an input range of ±1V and has three-state

outputs. The ADS-118A has an input range of ±1.25V and

features direct adjustment of offset error.

These functionally complete low-power devices (1.8 Watts)

contain an internal fast-settling sample/hold amplifier, a 12-bit

subranging A/D converter, a precise voltage reference, timing/

control logic, and error-correction circuitry. All timing and

control logic operates from the rising edge of a single start

convert pulse. Digital input and output levels are TTL. Models

are available for use in either commercial (0 to +70°C) or

military (–55 to +125°C) operating temperature ranges.

Applications include radar, transient signal analysis, process

control, medical/graphic imaging, and FFT spectrum analysis.
