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 (1.3 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 of ADS-118 and ADS-118A include radar, transient signal analysis, process control, medical/graphic imaging, and FFT spectrum analysis.
