GENERAL DESCRIPTION
DATEL's ADS-942A is a functionally complete, 14-bit, 2MHz,
sampling A/D converter. Packaged in a 32-pin TDIP, the unit
contains a fast-settling sample/hold amplifier, a 14-bit
subranging (two-pass) A/D converter, a precision reference,
three-state output register, and all the timing/control logic
necessary to operate from a single start convert pulse.
The ADS-942A is optimized for wideband frequency-domain
applications and is fully FFT tested. The ADS-942A requires
±15V and ±5V supplies and typically consumes 2.2 Watts
