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.

–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).
