12-bit, 2MHz, sampling A/D converter. Its stan-
dard, 24-pin, double-width DIP contains a fast-
settling sample-hold amplifi er, 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.

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 and
extended commerical (–40 to +85°C).
