FEATURES
GENERAL DESCRIPTION
DATEL's ADS-117 is a functionally complete, 12-bit, 2MHz,
sampling A/D converter. Its standard, 24-pin, double-width
DIP contains a fast-settling sample-hold amplifier, a 12-bit
subranging (two-step) A/D converter, a precision reference,
three-state output register and all the timing and control logic
necessary to operate from a single start convert pulse. Digital
input and output levels are TTL.
Total harmonic distortion (THD) and signal-to-noise ratio
(including distortion) typically run –78dB and 70dB,
respectively, with full scale inputs up to 100kHz. The ADS-117
requires ±15V and +5V power supplies and typically
consumes 1.6 Watts. Models are available for use in either
commercial (0 to +70°C) or military (–55 to +125°C) operating
temperature ranges.
